I find it interesting that the principles of the affordable care act were almost entirely conceived of and proposed by the Republican part back in the 90s in response to the Clinton health care reform initiative which failed. And no matter what they claim, a Republican administration in Mass (Romney) largely implemented much of the ACA on a state level and it worked very well indeed. Why it would suddenly become so repulsive to Republicans I do not know.
During the time of the passage of the ACA, my coworker, who was going through cancer treatment and other health issues read the bill in its entirety and he felt it was not at all perfect but it was better than what we had. A lot of the FUD going around (still is) was just that. He was comfortable with the bill as passed, even if the majority of congress critters seemed to not be familiar with it. I'm glad the supreme court upheld it. It the Republicrats want to get rid of it, they need to do it the proper way, and replace it with something better. No, going back to the status quo will not work. If they would propose a better, more equitable plan, I would support it. But so far they seem to be offering absolutely nothing. If they manage to get the White House, it will be over a campaign promise to roll things back to the good old days and then do absolutely nothing. The last part sounds good actually.
During the FUD and absolute crap going around during the passage of the ACA, many people talked about socialized systems in other countries (who was it that said they'd move to Canada to get away from the ACA?). The irony of all that is that between the VA, Medicare, and Medicaid, the US gov't runs the largest socialized healthcare system in the world. And it's one of the most expensive. Maybe the gov't should merge them all together into one program, and then require all federal employees, including elected officials and the president and all his advisors to use it as their primary health care insurance provider and system. You can bet all the problems would clear up in a a matter of months! And it just might end up being a really good program.
