>Second, your comment could be interpreted as saying that counties with high pay have (or should have) a lot of homeless people, which seems insane.

Does it? Countries with high inequality I'd expect to have a lot of homeless people.

Except if you mean countries with high pay across the board. So how does that work, everybody gets high wages, and companies can afford it and hire the same number of people, (instead of the case of splitting wages more equally)?

It’s not that insane. If pay is low then companies can afford to hire more people to do the same amount of work, leading to overall more employment and then presumably less homelessness.
