From what I understand it, UBI (as proposed by Andrew Yang) will give a lot who are not receiving any money whatsoever (from any government programs) income they didn't necessarily need.

aka, he is proposing to give both impoverished people and billionaires UBI

And then people will vote in parties whose position is ever increasing of the dole and it's a swift race for he socialist bottom.

A pipe dream that doesn't actually reflect human behaviour just the inclinations of some to demand others' things while calling them greedy.
