I’d think 100% would support paperwork relief.
But once you get single payer, you get price controls. I’d think the long-term trend would be for physicians who paid their own way through medical school to retire early, and for the government to get involved in financing of medical education, with moderation of financial returns for doctors.
If the English NHS is any guide, quality and availability would eventually drop. At first, it might seem good to many patients, because of the elimination of hassle. But you’d be taking advantage of a temporary surplus of doctors as you cut their earnings. As I like to say, “It’s always a party when you’re eating the seed corn.”
There is no surplus of doctors. The AMA and medical schools (and often medical school "feeder" universities) have been restricting supply for at least fifty years (since I was in grad school in the 1970's, and probably since WWII).
You forget that we have crony capitalism here, run by GOPe.
Once you have established both a monopoly and a monopsony, the opportunity for corruption grows enormously. Campaign contributions would escalate in return for favorable treatment of medical costs.
I used to think health care costs had about topped out when it reached 1/6th of GDP, but now it is 1/5th. I don't see why it couldn't be 1/4th of GDP, or more. Of course, housing, transportation, education, food and consumer products industries would have to take even more cuts, but hey, why not?
Once you have 100% control by the federal bureaucracy why would you expect any paperwork relief? What does bureaucracy do; what is the one thing it is actually good at? Why generating more bureaucracy and hiring more bureaucrats. And with the bottomless pit of US healthcare revenues to raid to pay for it, well, baby, you ain't seen nothing yet.
