In a way the guy before you is right: Some things would crash. For example, if everyone has a million, people wouldn’t be forced to do horrendous things for no pay. For example, nobody would work at a brothel, sell drugs or work as a modern slave picking fruit on a field. If people would do these jobs, they’d only do that for much, much more money.

But these things are things that only exist (at that price point) because enough people are currently desperate enough to be exploitable. In a somewhat just system, these kinds of exploitation shouldn’t be possible.
