It is certainly a market, but I wouldn’t call it a free market.

Healthcare, like real estate, is a dysfunctional marketplace lacking real competition

US voters have no principles. Even republicans started artistically screaming about nationalizing companies when they didn’t want to play ball with the president.

I'm assuming you're European and just want to make an "America bad" post because this is comically ignorant. There wouldn't be mountains of federal code to adhere to if that was the case.

This is a trope among populists: pass legislation around <thing>, observe consequences of doing so, blame the "free market", repeat.

Can you provide evidence for the claim? Polling from pew and Gallup suggest this isn't the case.

I think surveys show voters prefer the opposite, but certain powers are able to overcome that.
