Obamacare did do some good things that needed to be done, but essentially, everything about it was a bandaid intended to kick this shitty system down the road to the next person who had to deal with it. But hey, at least health care companies can't just turn you down because you have Diabetes or are too fat anymore.
I'd think education is the way around this. Start off with a "whats the worst case that could happen" then move to "whats the best that could happen." To me, you can convince people as long as you explain that their not going over a cliff. To me, this argument was never made. All I heard on the news was "it's socialism" or "it's good" but no selling the public on why it was in fact good. In this case, our leaders who were the proponents of single payer failed us. Single payer will happen, it'll just take a bit longer. The commercial healthcare industry is on a path to failure....there is no fixing it for the US. Eventually we'll end up with a system, that likely looks like what Germany/UK have (some mix of public/private).
