Elon Musk calls homelessness a 'lie' and 'propaganda'

And those are not all of the homeless. They are what Musk sees, because they are indeed very visible, especially in San Francisco. But he's making the classic tech-bro mistake of imagining that he knows everything, and what's not directly in front of his eyes doesn't matter.

Those chronically homeless -- the drug addicts, the mentally ill -- are indeed hard to help. Just building more housing won't help them. Even giving them free places to live is often of limited utility. (Unlike the large majority of homeless, who will be able to use it to get back on their feet, and will only be homeless for weeks.) There are ways to help, but they won't be found by just guessing based on what's directly in front of you.
