The alternative for many is worse - many roommates, incredibly long commute, or homelessness. Remember that Googler who lived in his car? (https://www.businessinsider.com/google-employee-lives-in-tru...)

The alternative is to literally just let developers build new properties. That's all you have to do. Upzone. Stop with the rent control. Stop with the mandatory parking minimums. Stop with the NIMBY bullshit.

This alternative being "kick people to the curb"

Its hard to build over top of places that are already being lived in, and once you kick those people out, you have even more people that need a new place to live

That said, if you're going to kick poor people out of their homes for the sake of rich moving in, why not just have the rich people live in those homes and call it a day?

I don't know what type of treatment you mean. I guess you're thinking on a guetto, which is adressed in my first message.

Also, people apply voluntarily. You're free to live in a private-owned rental
