dr. john mendelson from the university of texas. hospital was named the top cancer hospital in 2009 for the "u.s. news & world report" annual survey. also with us founder and ceo of universal health services, which is one of the largest hospital management companies in the nation. it's a pleasure to have both of you with us. mr. miller, since you're with me, let me start with you, why is it hospital costs are rising more quickly than any other specific piece of the pie? is it as simple as uninsured people go to the hospital as their first point of care, and that's expensive, or is it something else? >> well, we do have a bad debt problem. it's about 12% to 14% in most hospitals. but i think it's a question of technology and new facilities and increasing demand on hospitals. population is aging and there's increasing demand in hospital. >> so they're able to charge more, supply and demand. >> if you are able, you have to charge more. >> dr. mendelson, would you agree those are the reasons? >> i would agree to that statement. of cours
