We have the money, it's just flowing into making the top 5% comfortable and the top 0.0005% really comfortable.

Real estate in particular (but there are others) is a bottomless pit that society dumps money into, and speculators scoop money out of.

Just try and calculate. The rich are rich, but there are too few of them. Even $1000 UBI (which is not enough for anything) is like $3.2 trillion per year. All the rich taken together do not earn this much.
