Plenty of people have worked excruciatingly hard and never done drugs but wound up homeless anyways. Reducing homelessness to laziness and drug addiction is a good indicator that you aren’t familiar with the the literature around homelessness and might have some prejudices against homeless presenting people.

Tangentially, I think it’s much better to use people like Elon musk, or Donald trump, or Sam bank man fried, jk Rowling, etc as examples of who not to become. Bad luck can befall anyone whereas these people woke up and chose violence, repeatedly.
