If you want to do something about homelessness you will need to address vagrancy laws.
You will need to accept that not everyone wants or will benefit from a home. Not in the way that we think about home, this peculiar, particularly western way that we think about home.
idk who needs to hear this but you are significantly closer to being homeless than you will ever be to being a billionaire, have some class solidarity and stop glorifying your oppressors
