It's like a game of Monopoly where everyone gets more money, including the people who already have Board Walk and Park Place, etc. #WWJD? Flip the board over. Jubilee.
UBI doesn't have that property at all. UBI consciously, intentionally, and overtly transfers money from the net taxpayers to the net benefit receivers. (I support it, but it's absolutely an income transfer mechanism from the higher income to the lower income populations.)
The fact that the "rich" also receive $650/mo in UBI is completely swamped by the fact that they'll pay $30K/month or more in income tax to fund the program.
