50+ years ago, the U.S. decided on a "employer-based" health care compromise instead of a government-funded one. For a variety of reasons, that system appears to be breaking down. The Democrats appear by and large to be pushing for the government funded version as the replacement option, while the Republicans appear by and large to be pushing for individuals to supervise their own health care insurance (as they do with other forms of insurance). One increasingly likely compromise is for the government to mandate (and provide tax credits to fund) base-line insurance provided by a series of regional exchanges of private providers and then to allow individuals to "buy-up" from there. That's not my personal preference, but I'm betting that that's where we eventually end up some 5-10 years from now.
