Yeah. I believe in free markets so I must be a nut. What the fuck ever.
Nah, man. Free markets are great! But what you're asking for is TOO free, and has historically resulted in worse outcomes for people. Markets need rules, like "no stealing" and "no blackmail" and "no monopolies". People need to have the protections required to participate in a market, which includes the power to have their contracts honored, their disputes resolved by a higher authority, and their means of payment protected.
The US economy has been so wildly successful precisely because it has been able to thread that narrow path between too much regulation and too much anarchy. Markets where strongmen and criminals rule the roost do not generate huge profits for everyone. Markets where the government takes all profits also fail. You (we) need to find that middle ground, to seek out the path that helps everyone succeed.
Lots of countries don't have fiat currency, or a court system, or police to deter crime. Lots of countries don't have any taxes or market regulations at all, and as a result they rapidly have no widespread profits to protect because they have no capital to invest, no companies to generate revenue, and no shareholders to turn those profits back into the demand that drives more sales, more revenue, and more capital.
American Capitalism, despite it's flaws, is hugely profitable! That's because the US government collects taxes from the most successful market participants and uses those funds to protect and expand the marketplace for everyone. If we took away the source of capital (debt) or tried to curtail regulations (the bathtub) or starved the taxes (theft!) the system would fall apart. By advocating for these archaic policies, you are actively undermining the very things that have made America so successful. Why do you hate America so much?
So no, you're not a nut for liking free markets. You might be a nut if you want markets to be so "free" that they can become dysfunctional, in which case you're not really a "free market" kind of guy so much as you are an "anti-market" kind of guy.
Healthcare can work the same way, because healthy citizens participate in markets. Sick people, injured people, hospitalized people, addicted people, depressed people, these folks don't work. They don't generate profits for their corporate overlords, they turn from a national asset to a national liability. Good healthcare, just like good education, can turn those liabilities into productive taxpaying worker citizens. As long as they generate more value for the economy as an aggregate population, than they cost in healthcare, then it absolutely makes sense for the government to raise taxes to provide that care. From a macro-perspective, it's just capitalism protecting itself. This is a case where we apparently need more taxes and more regulation, not less.
