I think that if you have a single payer system and an opt-out for people who want to pay more [for better service, etc.], I think it would be better - and I think we'll eventually get there. It wouldn't be better at the top - [our current system] is the best in the world at the top. But the waste in the present system is awesome and we do get some very perverse incentives.
