Single Payer will screw the middle class of the whole world. Presently they can maybe get to the USA when they can't get treatment in their home countries. When US Health Care goes, well...
When USA goes to S.P. then research will peter out because then it becomes another cost to be balanced with Defense and the Dole and all the other things the government pays for and politically not the most important cost. When research ends, antibiotics gradually reach the ends of their useful lives then are not replaced after which Medicine is back to 1910 or so i.e. you get sick you die.
I've been mixing it up with some dumb ass Canadian trolls on You Tube and they think their socialized medicine is the greatest thing on Earth. But all of them avoid the question about how come when Canadians need real health care and major surgery they all come here. Some of them tel that's all bs and they get the care they need right away. I'm not buying it.
