Build more of that good ol' free housing that capitalism loves to provide?
The studies have been done bro, there is only one solution and I just described it
Also we don't actually live in a capitalist system, health care and housing are already socialist in many many ways. It would be easy to pass govt regulations making it easier to build housing. Capitalism is not the problem because we don't actually live in a fully capitalist society dude.
A lack of affordable housing compounds the challenge, but to say housing is the only solution when it isn't even a good partial solution misses the entire problem.
