I am all ears. Besides requiring insurance purchase, public option, or just going 'single payer' and raising taxes to cover it, what do you propose? Can we slap price controls on doctors/hospitals? Somehow, I think the 'free capitalism' crowd wouldn't be for that either. Less profit may also cause fewer doctors and innovation. Like I said it's a big mess and I am truly all ears.
I made a
brief post in the other PPACA love-fest thread (Europe is baffled...) that touches on a couple points. It was hardly comprehensive, but then again nothign I post will make a difference anyways... I'll just give some of the more fundamental reasoning here.
The thing about "Free market" lobbyists is that they are all lying. No capitalist actually wants a "free market". The term itself is generally a massive slegith of hand when used by anyone in a position to write a press release. To economists, "free market" usually refers to a market which satisfies some basic criteria from which it can be shown that a market equilibrium is optimal in some sense. When these criteria can be approximated reasonably well, the resulting outcome is generally very efficient. The problem is that in order to keep a market close to competitive (in the economic sense, not the marketing sense), you actually need pretty robust regulation. At the very least you need it to prevent price discrimination, and in markets for complicated products you need it to keep appropriate information flowing. These two issues pretty much define the American health insurance market, and the situation has been made worse by PPACA.
The economic term "free market" has nothing to do with what anti-regulation lobbyists want people to think it means. This is because no capitalist actually wants to operate in an economically competitive environment. In media print, "free market" means take out the regulations we don't like, but keep the ones that allow us to behave anti-competitively. This explains why the Republican party is generally bereft of good ideas. It's not because making a private system operate efficiently (yes, even one with a decent safety-net beneath it for the poor) is so hard, but because there is no deep pocketed lobbyist with an incentive to push for sanity within a private system.
