carol: businessweek, i'm taylor riggs. there inside the magazine's headquarters in new york. in this week's issue, china's new gateway into europe. a billionaire working overtime to impeach donald trump and youtube having its worst year ever. all of this straight ahead on "bloomberg businessweek." ♪ taylor: we are with the editor-in-chief of bloomberg businessweek and a fascinating

story is the cover for asia, right? it takes a look at the malaysian prime minister. bloomberg got an interview with him. jolt: he hasn't spoken in three years. we were especially interested in talking with him because this was a couple of weeks before the election in malaysia. and ifure thing for him, you have cap deny on malaysia, it has been rocked by this 1mdb scandal. lingeringl kind of carried there are investigations happening. the fbi has been involved in some of it, but here we are three years later. he has not been very public and now he is up for reelection. carol: talk about the scandal, because we have covered it a lot, but remind us. joel: this is a development fund that allegations were it was used almost as a slush fund.

it was mentioned as one of the people who might be affiliated with it. as one of the crackdowns, he has really cleared the decks and has asserted himself. taylor: what do his proponents say? he came out and said i have a very strong support base, even with some of the scandals going on. --feels can fit and confident. what do his supporters say? joel: what's more impressive is three years ago, it would have been unheard of the you could have said his name and reelection in the same sentence. he is definitely a front runner in this and they like that he e hold on power. he is very assertive. the economy is bumping along, but this is a massive economy with massive potential. here is a chance to have stability. one of the amazing quotes he

said was "change." the malaysian economy is doing fairly well. unemployment is low. the thing is, his party has not been able to get a majority. they have had some stumbles politically the last few years. joel: including the 1mdb scandal. alay, theye average m don't even know what a bond is, much less what 1mdb does. it is a very complicated financial transaction that we are still unraveling three years later. about that is crazy too is all of a sudden, $700 million showed up in one of his bank accounts. he said it was a gift from the middle east -- >> a lot of finger-pointing. i think of him as almost the teflon politician. you cannot throw a bigger scandal on anyone and yet, here he is. that is why we chose the cover

line "the survivor." taylor: the u.s. cover is youtube. it started out with a sad story, the shooting that happened a few weeks ago and then youtube taking a broader crisis and what they are facing, and there controls and the privacy and the videos they allow -- walk us through the cover story. fascinatinge is a story because it has had hypergrowth. 450 hours of content that's uploaded to the site every minute. it is staggering how much content is on the site. in the past year, it it has had a very bumpy, missy year. there has been a lot of fallout over unsavory clips and it goes tom isis propaganda prominent people taser ring -- tazing rats.

from a strategy perspective, the biggest competitor they have his television. television is heavily regulated and yet, here is youtube, not regulated at all and even struggling to put in a cleanup plan that helps them. that is where our story picks up. here they are having this gigantic mess, a highly profitable year, but what is the plenum -- cleanup plan going forward? carol: we have more on youtube having its worst year ever. going backpast year, to last march, youtube has dealt with some type of crisis every couple weeks, every month. more of a public relations and marketing perspective carried the business has continued to grow by leaks and -- leaps and bests because it is the place to reach someone between 18 and 34, but what has been one

of the greatest things about youtube, it is this democritus sizing force, anyone -- democracy force, it has also become an achilles heel because people are paying so much attention to all of the bad video circulating on youtube. that has been everything from the "youtube stars" who say inappropriate things, some last marchc remarks kicked this off. logan paul, another prominent youtuber filmed himself in a forest in japan known for suicide. he filmed a dead body and then films himself tazing dead rats. you have advertising running from blue-chip companies running in front of terrorism videos, white supremacist videos. an inappropriate kid video -- name it, you have probably seen it over the last year and they have gotten in trouble over it and are trying to figure out how

to balance their desire to maintain this open platform with the need to censor or silence some of these inappropriate or darker impulses. love: you ask a question i -- is youtube inherently flawed? to have anot awareness of some of the problems that are out there and what is going on, but do they want to fix it or is this just the way it is going to be? lucas: the problem they have is they have competing desires. youtube wants to be the biggest online's -- source of online video advertising in the world and is, but it wants to grow and grow. it wants every major advertiser, every major media company. it wants to catalog everything. it wants you to to be the video network,eo social video search engine for the world, but it is hard to have everything and satisfy the top

advertisers and charge them a high rate because if you are a kid friendly advertiser. if you are selling diapers, d1 your diaper ads to run against some of the most disgusting videos you can see on the internet? you don't, so they need to find a way to make those happy. i know they haven't figured it out. they are at something of a crossroads. what i like to view as a nexus that because i think they have to make some choices between those two. islor: this week's cover youtube. walk me through the process of making the cover. >> we wanted something that got at all of the different things, the uploads and how some of them are causing problems and they are having to clean up. taylor: you did the cleanup job, i see a file of trash. of theanted all different things and there are easter eggs. we have tied pods, a little bit of everything to get people to see there is this big problem

and they are trying to clean it up. love is itt i also looks cluttered and that is part of youtube's problem. you can upload tons of videos every day. they almost don't have the time to go back and filter through it before all of these videos are put up on the website. that is clear here, just the clutter of it all. chris: it gets at the overwhelming nature and that they have this big problem to deal with. next, apple tries to play catch-up with google and facebook in india. security researchers can be greedy too, but is that bad? this is "bloomberg businessweek ." ♪

businessweek.com and our mobile app. in the technology section, we go over to india, the world's fastest-growing smartphone market. apple is going over there to attract kid coders. here is jeff muska is. only two isrst of now up and running in bangalore and the past couple of months, have been trying to teach young people in india on the kids as 9 through:00 -- 7, high school, how to better tailor their software development careers for the app store. a kid carded -- started coding on his seventh birthday and already has a fairly successful tonslation cap -- app

convert measurements. carol: these kids get to learn to code and create apps. what is apples take? they want to get new apps or e into their system? how does this work for apple? jeff: one part of the pitch for apple is to look like an inviting place for developers to code, but a big piece of that is catch up. the 125 million smartphones sold , making in a given year it the fastest growing smartphone market in the world and the second in absolute terms only to china. out of those phones, apple is selling about 3 million? anything, they are losing ground to android in this market. losing talented developers not only to google's ecosystem, but to facebook. there have been pushes from mark zuckerberg's team to get people to code for facebook. , they aret is cool is

tapping into india where there is a very young population and a lot of developers. that is one thing, but they are also thinking about the young population that needs to buy phones? into the appleet ecosystem. they are playing two different things here. around the world, apple is focused more and more on services and revenue from areas beyond hardware sales that they didn't have to worry about a few years ago. is tough to talk people in a market with so many cheaper options than the iphone available, to start coding for apple. the sales pitch has to revolve around the kind of customers you are attracting. -- i heard from a bunch of kid coders and apple is quick to assert that while

using themore people android store in india, the people using apples's app store are more likely to pay you. taylor: in the solutions section, we talk about the security company cps -- they information and sold it to short-sellers. we are told that is unethical. we get the scoop. they were that researching for about a year when it claims were some vulnerabilities in amd's chips, one of the biggest after intel. so ina very large company mid-march, i guess, c.t.s. sent a note to amd saying we have -- something on the order of 13 vulnerabilities, and the issue that developed was went public with

this information in a very short period of time. in the world of discovering bugs and going to the companies that you discover those bugs at and making them aware of it, there has been a custom that has developed over the years in which people typically give the company the right for a period of anywhere from 30 to 60, 90 days to decide how they will approach the vulnerability. gave amd less than 24 hours. it turned around and went the -- went public and sold to short-sellers who make money. what we have here is a really interesting ethical dilemma in this world of bug discovery. how it happened until now. it is fascinating and raises a lot of thorny issues. when do you disclose and how do you disclose? what is appropriate?

in the name of security, what is the best thing? carol: cts is set up as a business to find these bugs and typically, the hardware makers have bounties they will pay. there is that relationship between the companies. dimitra: exactly. in this instance, there was no bug bounty. , given the other way it makes money off of what it is finding, is being paid bug bounties. that is something we don't know. there is this whole practice, because when you are discovering something like this, you are letting a company know something that is extremely important and very valuable to them. in a way, they are rewarding that. also, they are encouraging people to come forward with what they find. the time period you are tearing -- typically waiting isn't just to give you time to figure out your pr strategy. these are complicated, difficult

things to deal with. you don't want to go public right away and give hackers with bad intentions the opportunity to use the information just made public and in some way, do even more damage. damage,ts could do more they could sell it to the black market? dimitra: theoretically, yes and there are people who have strong reactions and believe cts acted very unethically and are handing this information by the way they handled it to any bad actor who wants to go and do whatever they want to do with this. taylor: next, cyprus finds it self at a strategic crossroads for china and the threat of a trade war is a wake-up call in pharmacy. this is "bloomberg businessweek ."

♪ welcome back to "bloomberg businessweek." you can listen on the radio,

serious xm channel 119, a.m. 11 30 in new york, 106.1 in boston, washington, d.c., a.m. 960 in the bay area and in london on dab any wrecks three and in asia on the bloomberg radio plus cap. in the economic section, we go over to cyprus. they found a new trading partner in china. sees it as a way to expand its footprint in europe. we get the scoop from our editor. christina: cyprus and other european companies have been coy about selling the china. it has allowed a lot of investment already and it is a --ll economy, so it takes admittedly, we have a source saying a drop of chinese money to make a big splash in a place like cyprus. it is also a company that -- country that traditionally has

less control on a lot of things than countries like germany and france. some people have casted a weak link in fights over money laundering and things like that. carol: what kind of things has china invested in him in cyprus? cristina: a lot of infrastructure investment, ridge -- marinas, a capital injection into the flag carrier, the airline. announced, itest hasn't started yet, this big integrated casino resort that is a $670 million project and it is supposed to be the biggest in europe. carol: china money funding it? cristina: yes. taylor: when you mention infrastructure or investment, usually that can be a good? , butnvest in the economy there is fear around this too. walk us through the fear.

cristina: the concern is that once a country becomes -- owns asset in aa critical place, it can start using that influence in other arenas. we have already seen, for example -- there was an interesting case in which greece, during its crisis, china came forth and bought government bonds, which was a sign of confidence. it was meant to signal to the world. later on, theat european union at the u.n. was drafting a resolution to criticize china's record on human rights and greece successfully blocked the resolution. it is about buying influence, in a sense. these are productive assets and there are good reasons china would want to invest abroad. but also, it is a way to extend its power. session,n the politics

we get the latest on the chinese iniffs making republicans farm states nervous. we will see how that affects the midterm elections. matthew: this is a look at farm state republicans and how nervous they are about the backlash of the chinese tariffs that have been put in place to retaliate against the tariffs president trump put in place against chinese goods. they are going to take this harder than anybody else in the country and this is a core area of trump support. so we go to iowa and kansas and talked to farmers and members of congress who tried to gauge how worried they are and they are pretty nervous. carol: how worried is republican sting -- steve king of iowa? matthew: probably more nervous than he would let on. steve king is the congressman from the fourth district of iowa.

i many measures, the top agriculture producing district in the country. if you want to know what farmers are thinking, you go there. steve king is as strong a trump supporter as you can imagine. so are his can chew its. they voted up by 27 points in 2016 and yet, they are going to take the brunt of this as much as anybody. a lot of soybeans, a lot of sorghum, two products china has put tariffs on. at of the 30 congressional district that are soybeans, 25 of them are currently represented by republicans in congress. all of them voted for trump. we wanted to go and gauge how concerned they are about the backlash. this is a market that is already having low commodity prices, so they are already dealing with low farm income on top of having

179% tariffs levied by china. they are really worried about what this is going to do to their economy and republicans worry about what they -- that will do to turn out in november. tolor: when you say you went iowa and kansas and talked to these farmers on the ground, what was the tone and the sentiment? there are pretty heartbreaking stories in there. matthew: they are pretty worried. a remember in 1980 when jimmy carter protested the afghanistan war with grain and crop prices crashed. that was the beginning of the early to mid-1980's farm crisis. there were lots of bankruptcies. it didn't just hit farms, it hit entirety economies like places in iowa and missouri. that is fresh in the minds of a lot of older farmers and certainly their kids, who own these farms. on the policy level, the thing we are interested in with this the words of one

senior republican strategist, this policy is like micro-targeting pain to your most staunch supporters. this will be a test of allegiance that farm state republicans have to the president and it is no prize he did this, because he was talking about trade and protectionist campaignall on the trail but that was aimed at more rust belt blue-collar factory workers in places like michigan. not farmers. farmers love free trade because they can sell their weekend corn and grain all the way over the world. it is not the manufacturing industry that will get hit by the chinese retaliatory efforts as it is the farmers. carol: next, the campaign to remove donald trump from the white house. plus, the board games that are the most popular in board rooms. this is "bloomberg businessweek

taylor: welcome back to "bloomberg businessweek." i'm taylor riggs and we take a look at the latest dealmaking trend in the food industry and tom steyer's campaign to impeach donald trump, and a facial mask made from outer space. all of this still ahead on "bloomberg businessweek." ♪ taylor: we're back with our "bloomberg businessweek editor-in-chief joel weber. in the business section, we are

talking about a company traditionally that does a lot of m&a to fuel growth, but they might have to turn organically growth. walk us through the company. heinz happened about a year ago and markets loved it because 3g and buffett had teamed up. 3g, brazilians know what they are doing and they come in and cut cost and markets love it because they invigorate this. the thing is, it really comes makingrom them acquisitions. kraft heinz, mayo, ketchup, what else are you going to do? massivee rebuffed in a takeover target. they wanted to go after unilever and markets loved the idea because they thought this would be all this cost, and -- cost cutting and yet, it didn't go through. unilever went through and now

kraft heinz is left reeling. carol: here it is, a huge packaged food company and they have to be a huge packaged food company all of a sudden, but it is not a lot of growth. joel: food in general, very thin margins. packaged foods, as consumers have shifted taste away from packaged foods that sit on shelves -- it is a question of, where is a company like kraft heinz going to see growth? taylor: what is their story? are they going to push for organic growth? are they going to try and go into something more sexy that millennials are buying in stores? joel: it is all eyes on them because this is just after the unilever thing didn't work out. now markets are looking at this and saying, this is a company that was basically built on private equity style takeover financial engineering. are they going to be able to find something different, or is it going to be a different kind of kraft heinz going forward? carol: you see some of the deals

happening in the packaged food business, especially upstarts and general companies -- a lot of people want them so valuations are going up. joel: exactly. from -- it will be driven by consumers. where are consumers going to put money and especially when you start thinking about shifting consumer habits. you see meal services that deliver inboxes. you are not buying hot dogs anymore. that is a change in habit that a company like a kraft heinz really isn't going to benefit from. ditto on the grocery side when amazon buys whole foods. how is that going to disrupt what they do? carol: let's go to features. who hasan individual reinvented himself several times. the billionaire turned activist turned someone on a mission to impeach president trump, tom steyer. joel: billionaire democrat.

he seems to have some political ambitions. need formessage is the impeach. impeach donald trump. is one that democrats kind of winds at -- wince at, because it divides the party of people who want to have that conversation and others who say it is the wrong conversation. it is a divisive person who has taken one side of the issue. taylor: we heard more about tom steyer. max: he is a billionaire, for one. one of the biggest hedge fund managers in the world. 2008 -- but he quit and became something totally different, which is an environmentalist. ist is not what the story about. there is a pretty good story about that era. he had another reawakening.

there has only ever been one max, but there are three tom steyers. he has become a national political figure and is mr. impeachment. tois the main guy trying light the fire to have trump thrown out of the white house. taylor: how did the campaign start? carol: take us back to february. max: first of all, have you two aer watched tv and 60-year-old guy in front of a fireplace like, the country is in terrible shape, join us. have you seen that? carol: it is pretty ominous. max: if you talk about the strings and camera coming closer and closer. carol: just a list of things that are wrong. max: he came out with this ad and put it on fox news, who saw it -- donald trump. insulted tom steyer, called him a crazy

billionaire and sign-ups for his list ballooned. what he now has something substantial. 5 million people signed up for "need to impeach." he has promised $40 million for the effort. in addition to that, he is spending $30 million to get millennials to the polls in november. all of a sudden, he is this major political force in america. want to talk about who are the supporters before we get to the opponents. who are the people who are signing up and supporting the campaign? max: i went to washington, d.c., the national press club -- you can throw a baseball and hit the window of the oval office. filled -- now we are going back to february -- in february, i was in washington and was in vegas -- we can talk about that -- but in washington, he had these fans. trump has some supporters who

are absolutely in love with him, but i think it is fair to say there is a large swath in this country who believe we are headed for some constitutional crisis, let alone something areier and those people glad to see someone like tom steyer say "politicians need to act." in a way, think of him as able mourn for the frustrations and anger -- bullhorn for the people who can't believe that this reality tv star is the president. taylor: and the demographics? max: it is fair to say republicans tend to be older and hiter and more mail -- male. you asked about opponents and one group are trump fans. they think he is a george soros character, a puppeteer in the shadows -- he is a rich hedge mention and i can't not

he worked for goldman sachs and morgan stanley. then he has another group of opponents, who are mainstream surerats who are impeachment is the right idea, or aren't sure impeachment is something to do now because the numbers aren't there. next, a pyramid scheme leaving a trail of unhappy women across the u.s. and what may be wall street's most popular board game. this is "bloomberg businessweek ." ♪

started this company that is called a multilevel marketing company like mary kay, herbalife, where women buy clothes wholesale from them and sell them retail for roughly double the price. mlm's andy are these then there are ponzi schemes. what is the difference? mlm's are legitimate, right? at the mlm's, someone top founded the company and got in early and built underneath to them. a recruit people to sell and they get a commission based on what the people sell. world, that commission is based on what people underneath them sell rather than what they buy. there have been a lot of court cases -- it was looked at closely to make sure it is based on what people are managing to move toward consumers rather than purchasing from a company like lularoe. but when lularoe first started, they based their compensation

wholesaleplan on orders. that changed last year, but for the first several years of their life as a company, they grew in or mislead because people realized they could make a ton of money if you recruit people to join your team. taylor: there are some problems ranging from lawsuits to inventory and merchandising problems. what are the problems facing this company right now? claire: lularoe is facing about a dozen lawsuits that are in various stages of litigation or settlement. one big one, and enormous class-action suit with 22 plaintiffs who had been former consultants with lularoe has recently this week been moved to arbitration. they were trying to say this is a pyramid scheme but in their contracts they had signed, they have to litigate everything through individual arbitration, so it is that way. hard to say what will come out of that because it is harder to win a case that way. carol: in talking to the

consultants, there were things like get your husband to quit their job, go all in on this, backhe profits to plow into the business so people bought more inventory, which is good for the home company, and also things about gastric bypass surgery? there were a lot of crazy things that went on. claire: this is largely a story who have started to have kids and switched either from full-time income to being a stay-at-home mom or part-time. they are looking for a way to still earn money and support their families, and also feel like they have some sort of business. markets itself as a business opportunity for people. they say you can help support your family, work from home and take care of your kids, that is why there are so many people willing to get in on this. in the pursuit section, we are looking at boardgames

at boardgames for collaboration and networking. this has so much more going on than just boardgames. mark: the story came out -- i --e a great friend who is has a hedge fund. , and nerdy and loves this he has a great connection with a lawyer. she recommended a pro bono company, and it unspooled, where i recognize they are playing board games, but as a way to hang out, meet people, maybe get new jobs. one guy said i got the best job of my life from a guy i roll dice with. carol: it is a way to test a future colleague, are they a good loser? mark: that is what i love about it because, would you want to work with someone who flips the table? i wouldn't. carol: you said catan. our producer loves that. what is this game? isk: settlers of catan

essentially silicon valley's favorite board game. it kick started the modern boardgame trend. because it is a game of entrepreneurship, for you to be good at catan. to be good, you have to be an entrepreneur. it really dovetails with a lot of what makes you good at business today and that turbocharged this wall street white-collar boardgame night. taylor: what makes you go to business today? do i have to be in finance to do these or there are a lot of industries and people are excited? are: the board gamers white-collar people, lawyers, doctors, financiers -- conventional white-collar workers. these games aren't just about winning at all costs on your own. a lot of them require you to collaborate with other players and maybe learn to put your own needs first, pivot a little. it is about being nimble and

by a man who was the former dean of the gale school of architecture and he designed the ellen called 15 central park west in new york that was completed in 2008 and new yorkers and international buyers went crazy. carol: how come? james: this is a great question, and one of the easiest answers is this was a condominium as opposed to a co-op. that isis a building owned cooperatively, an abstract concept but most importantly, co-ops typically do not let use thesenal buyers or let people buy and sell. there is a huge vetting process. carol: it goes before the co-op board? james: completely. with a condominium, if you have the cash, you can buy.

that is appealing to a lot of people who don't necessarily want to have all of their finances scrutinized by an invasive board and it is especially appealing to people who like the idea of buying it as an investment and sell when they want, as opposed to selling whether a board considers the buyer appropriate. the result, in the midst of financial crisis, 15 central park west did spectacularly well. they were setting apartment records. one apartment eventually sold for $13,000 a square foot. carol: here we are in the crisis and these apartments are selling like hotcakes. james: yes, so other developers look at this success and were we should try to re-create it. the other aspect is this is a building that looks like -- it looks gracious, prewar, it has all these elements that are

extremely attractive to people who like that "graciousness" of prewar living. it is not a giant open kitchen with living room and dining room space -- it is discrete, yet all new. it is configured to a more modern family. carol: are they doing well? are they selling as well as the original model? question.s is a some of the buildings are selling spectacularly well. are"affordable ones," which $2000 a square foot, so $3 million to $15 million per apartment. those are the buildings on the upper east side and the upper west side. those are selling like hotcakes because as one analyst said to me, they price them right so they are selling. when we get to some more expensive examples, this is a real question and a lot of

people are interested in the answer. they haven't listed any closings yet. there is speculation they are having difficulty selling because they are colossal. every apartment is at least one , 4500 square feet, more or less. it is a lot of space. taylor: like you said, it is not a co-op. you can get the international demand. a lot of these buyers are through llcs. james: indeed, and no is the easy answer. some people, regular professional new york class are not necessarily buying with llc. it is a doctor -- if you are a doctor or lawyer, you are not setting up a company. the it comes to things like $250 million penthouse is that are apparently being sold in some of these buildings, there

is a lot more ambiguity about who the buyers are. section,n the pursuit led masks are a growing trend in facial treatments and the science comes straight from space. here is reporter mark ellwood. about a nasaalking technology, which you have probably seen on instagram. you have probably seen on eartagram, celebrities w crazy masks that glow. this is called low-level light therapy, lllt. and it is derived from a nasa science about growing plants in space and firing infrared at them. it helped the plants grow faster. if they put it on wounds, it will heal faster and suddenly, someone thought if it heals wounds, it will fix wrinkles. carol: you have real companies

making masks that are thousands of dollars. mark: they are a one-time investment. bendable yogas mat with lights on it, that could be a couple of thousand dollars, but it won't cost you anything more than that. there is no maintenance cost. , each a dermatologist time you go, it will be hundreds to thousands of dollars. this is not a quick fix. we all want one, but this is laying there with tanning goggles over your ice for 30 minutes a day for a month. then probably once or twice a week moving forward. you've got to be patient. taylor: there is ance, wrinkles, what else? mark: it depends if you use infrared or blue light. settings thatous help with muscle soreness, joint

pain, the wrinkle thing is what i care most about that the companies do sell it as both a medical device and -- use. carol: what is the regulatory oversight over this? i am always concerned when there is lighting. mark: when i tried this, i was worried about my eyes. what is important to know is these are not lasers. -- i'll getffracted the technology wrong, but it is not a unidirectional light that would damage her eyes. are not medical devices, they are not endorsed or overseen by the fda. out withoutng it reassurance, but there is little harm they can do to you. they are more like interesting to leave -- placebos at worst. taylor: "bloomberg businessweek" is available on newsstands and online at businessweek.com and our mobile app. more bloomberg television starts right now. ♪
