Anyone that thinks it will be cheap and easy to implement a single payer system in the US should check out the ocean front property I'm selling in Arizona. And anyone that thinks the GOP could turn to it after they make a huge cluster fuck of things. L O fucking L.
There is no easy solution to fixing healthcare costs in the US. We are bounded by decisions made 1-3 generations ago, and the disparate interests of various stakeholder groups and the public today. If a single payer system came down from heaven tomorrow, a lot of people across the board would have to get real cool, real fast with making less money, having even longer wait times, and potentially facing even more (but different than today) "no"s for various procedures and meds.
