You also said, "Remember how much of modern medicine relies on technological advancement, and consider where innovation tends to come from, and exactly how much incentive companies are going to have to do R&D when the price and profit for their efforts will probably be set by DC. " A lot of innovation has come from countries with public healthcare (especially in a number of recently Canadian examples. ) If you meant, "consider where innovation tends to come from, but only consider it within a country with no public healthcare" then, yes, it's axiomatic that innovation comes from the private sector, but I don't see what that proves other than the fact America has no public healthcare, which we already knew.

Meanwhile, according to pharmaceutical executives the bulk of their overhead goes to advertising, not R&D, so maybe the problem is less non-existent US public healthcare than the drive for profits above all.

In my experience, recent and otherwise, pro-socialists typically point to disasters that prompted regulation and recurred only after that regulation was repealed by "free" market acolytes. And, yes, the point of the "vote yourself rich" claim is very much about trying to politically mandate prosperity; no one is trying to get ahead because they get public healthcare: They're just trying to survive.
