. >>> kavita, why are health care costs twice as much in the u.s.to other developed countries and when you look at life expectancy, it's higher elsewhere? >> you've brought this up, ali, and it's true. when you look at our per capita spending compared to health outcomes, america does just about kind of at the bottom of the eu chart and, in many cases, other third third countries are doing better than we are. that comes down to three reasons. number one, we have no checks and balances on what we're paying for. when you and i go to purchase anything else, we have a sense of how good that product is. we have very little insight into whether the doctor that we're seeing is a good doctor or a bad doctor. second, we actually have been burying the brunt of the costs for the world around drug prices, around the costs we pay for images, lab tests, hospital beds, you name it. so a lot of economists like to say it's the prices, stupid. and that's a lot of what we're paying for in health care. >> thank you both for your time. i appreciate it. we'll talk to you
