Earlier quoted context omitted.
The poor would soon learn their one shot out of poverty is keeping their job and throwing their UBI income straight into the stock market. This would propel the prices of equities to even greater stratospheric heights, and as the investor class gets richer eventually the prices of all commodities rise to capture this easy money flowing around. So now the poor have more money but it still buys less or equal to what it…
Any UBI is not going to be "in addition to" whatever other money you might earn, but is more likely to look something like a minimum income, below which you cannot drop (even if you stop working).
So we don't have to have bureaucracy to run it bla bla.
How is it UBI if I stop getting it if I'm working? Then it literally is just another form of government help to the unemployed and a massive disincentive to work.
