. >> in the united states people use examples from europe or canada, culturally more similar to the united states, these are much smaller places given the scope and size of an area as the united states, your thoughts? >> absolutely they can be applied to the united states. what i would suggest is that you know, the legalization of marijuana and the selling of medical marijuana in many saits istatesin america, if the tax ft could go into addiction centers for both drugs and also for alcohol, you then got a win all round. because in those states where legalization has taken place of marijuana you have not seen a massive uptake of people taking marijuana. and you haven't seen any massive increase in damages as a result. in fact quite the reverse. so then do it in more states, tax it and then use that money to help people who actually have drug problems or have alcohol problems. >> let me ask you from a business perspective. you are the ceo of virgin airlines, who continues to administer drug tests for safety person. $193 billion cost of drug arrests mainly due to lost productivity not crime.

much too high compared to europe or canada or even china.y all want to move towards a territorial system. they differ in how they get there. the healthy thing for the republican party is the agreement on direction. that said, i don't think one is powerly over the others. they move in exactly the right direction. the house and senate are thinking along the same line. any of these guys, you will get lower rates, lower business rates, a flatter system, expensing and territory. >> you would also get more debt according to the tax foundation which analyzed six of the presidential plans? they would each add at least $1 trillion to debt. >> tear are two things. you would have to look at how much growth would help. if you grow at 3% a year instead of the 2% a year that we have been doing under obama, you end up with $2.8 trillion each year. for ten years, you get 2.8 trillion dollars more revenue coming in. you can cut taxes quite a bit if those tax reductions get to higher growth up to 2% or 4%. while we are talking taxes, of why usually, obviously

that can be maintained in the united states can't be maintained in subsaharan africa or places in europe. i'm from canadanally so i do know people do drive across the border to take the lower-priced medicine. whether it's a way people are going to respond to this daraprin situation i don't know. but for the lower prescription drugs they do do that. then there's a question are you getting the real drug? sit a copy? is it safe? i don't know, i wouldn't want to make other people's decisions for them. but the problem people have to really look into is this: if the drug company that is legitimately doing research and development and i'll just say glaxo smithkline as an example, they have to put their capital at risk. cram down the drug price investors say you know what i'm not going to put my capital at risk anymore. >> professor joyce, you can't use production substitution as easy with medicine as you can with other consumer goods, can you? >> increasingly we can. we do have drug classes why we have generic -- where we have generic substitutes in most of them. daraprim is a six decade old drug, it was the on

or weren't keeping pace with the growth which we were able to do thanks to congress. >> which countries were those in. >> we were talking before, there's a group of traditional donors, western europe, u.s., canada, korea, japan, australia and new deland. collectively we were unable to keep pace. but i think the u.s. did its share. then there's the gulf states where they are -- sometimes some of them are charitable, particularly charitable and write big checks and sometimes not. they tend to give in very one-off situations. we would like to see more uniformed giving, routine giving from the gulf states. then there are other countries that do not make a habit of providing assistance through humanitarian assistance. they prefer to do other ways of engaging with the world. i mentioned china and russia before, two countries that are on the permanent five of the u.n. security council but they're not part of the traditional donors. >> it's probably an obvious answer but the democracy seem to do good in caring for other people and the dictatorships don't. so it kind of flows. they give to their own, they don't give to others either. >> it's called western donors. but now we see japan, korea -- korea ha
