I have seen estimates that as much as two thirds of healthcare spending actually traces back to the govt when you count subsidies too. It is a mostly-socialized system at this point.

And of course even where the govt is not funding the product, they are stipulating in detail what it must include. E.g. insurance must include a long list of things from mental health care to nicotine patches, forcing people to go through their insurance rather than through a market where they would negotiate prices.
