It's communist is the problem. Whose pile of money? If old Warren Buffett wants to spend a billion to extend his life by a year, who am I to stop him?

It's not like someone would forbid Warren Buffet from doing so. The government already set up a system that is all but in name compulsory. So, let's take a pile of the same size as the current system uses, but let it go through a single arbiter, with combined purchase power.

We have a system like that for student loans—where the federal government itself originates and owns 90% of student debt—and it has led to massive cost inflation. What makes you think we’d implement a healthcare system better?

Yeah, maybe it's a lost cause. America is kinda special.

In some sense we have that - what is covered by medicare and the insurance companies is covered for the relevant people in those schemes.
