@hunkyscotsman Strange question. How would paying more tax money for less-efficient healthcare help fund UBI?
The U.S. is the only major rich country without universal healthcare, and their governments together spend the most per-capita on healthcare (with worse outcomes), and then force many citizens to pay twice, buying private health insurance to cover what they've already paid for in taxes.
@hunkyscotsman On Marx vs Keynes, UBI would be irrelevant in a communist system, since everyone would already (in theory, if not in reality) have everything they need.
But by the 1930s, it was clear that both pure communism and pure free-market capitalism were untenable (except as political slogans), which is why rich counties today use blended systems, about 50:50 public:private economic activity, ±10% either way. UBI is a way to make the public part more equitable and efficient.
