Well, as I alluded to earlier, we have not had *actual* free market for quite long time and what get passed around as "free market" is actually more like corporatism. Not too removed from Fascism, where we had government supporting corporations.
Yes, and while you can clearly see that I have my idea of what would work, I do believe that regardless what we do, it shouldn't be at national level. Drop it a bit lower and boom, we now have 50 labs (or more, if we care to go lower than states) to experiment with what model works best. I'm sure some would adopt a more socialistic policy while other would leave it in private interests, with full stop for-profit motives. But we get to measure and copy the successful model. Also, if it's kept small, it's easy to measure and assess, and we can always fine tune for a particular locality needs.
But all the along, the debate has been at national level, and this is probably why we got nothing done. Too bad people are so conditioned to look to Federal Government first for any help on anything. Also, the fact that Feds already has butted in with their policies to date (e.g. tax breaks to employers who give out healthcare but not to self-employed) will make it difficult if not impractical until they abolish those laws & regulations. We definitely do need more of Barry Goldwaters in the Congress, IMO.
