Homelessness is heavily correlated with mental health issues, childhood (sexual) abuse, and/or childhood deprivation. A lot of these people were fucked before they even got a start in life, through no fault of their own.

It's easy to think they're in the position they're in because of some kind of moral failing. It's comforting, it allows us to pretend it couldn't happen to us. It's good for our egos, we get to pretend our relative success is a result of how great we are.

But the sad reality is that for a lot of people, especially outside the western world, life is fundamentally unfair and no amount of talent or drudgery will do much to significantly improve their situation in life. Realistically the most they can hope to improve their children's chances, and it's still a long shot.

Hell, it is almost certain that there are cleaners working at Tesla, who are both more intelligent and hardworking than Elon Musk. But they were born in the wrong place, to the wrong parents, and with the wrong skin colour and/or genitals.
