This is laughably naive, and ignores basically all of human history.
to believe that the government and worse agents with in the government has no financial incentive is crazy. It is absolutely the case that where are tons of both corrupt, and non-corrupt financial incentives with in the realm of public finance. Take a look at school funding, police funding, or the big one Military funding. This idea that medicine would be immune does not match reality even if we limit it to say medicare, or even COVID ...
your view that government only acts in "the best interest of he citizen" is also ignorant of history, in reality it is often the exact opposite, The nine most terrifying words in the English language are: I'm from the Government, and I'm here to help.
Government is not the solution to our problem, government is the problem
>>you're completely wrong about the ability to sue the government. There's no meaningful difference in being able to sue a company or sue the government. It's all the same court system.
No, I am not [1][2][3]. Both the federal and state government enjoy complete immunity from liability unless they agree to be sued,it was not until 1946 that you could sue the federal government at all, with the passage ot the Federal Tort Claims Act[4] the federal government graciously allows us mere mortals the ability to sue them in rare and limited circumstances but that authorization can be removed at any time, and often has been, and I have no reason to believe that congress would allow a single payer system to be sued for denial of care generally
