Saying the US embraces "capitalism" doesn't really make sense. What does that word really mean? The economy is proclaimed as a free market, but it is absolutely riddled with taxes, regulations, and crony privileges for corporate interest. Some say this, and not laissez-faire, is what they mean by capitalism, but conflation and confusion abound when it comes to economic discussions.
Where does the wealth for UBI come from? Governments produce nothing. It can only tax people who are productive, or create units of currency out of thin air. The inflation we are facing now is largely a consequence of COVID response money supply and credit expansion inflation we were told would be nonexistent or transitory four years ago.
Cryptocurrency is a threat to the monetary system of government, so they demand power to regulate and monitor our efforts to create a market alternative to their monopoly money. Meanwhile, central banks are trying to figure out how to create their own digital currencies so they can surveil us more and ensure they get every penny in extortion revenue possible. It's not for serving our needs.
Income tax was sold to Americans as a way to get the "1%" of 1913 to "pay their fair share," and the Social Security ponzi scheme was a guaranteed income for old age. Neither worked as advertised. A UBI would be different how?
