I reject the notion that this problem is even remotely unsolvable. I'm not saying it's easy, I'm not saying it'd be profitable, but it's not that hard. The reason it feels hard is that it gets politicized and PC'd super fast, which quickly penalizes any form of brainstorming. Here's some off-the-top-of-my-head brainstorming, that promises nothing, but is infinitely closer to fixing the problem than all the other comments I've heard on this topic in my life put together: 1. Move homeless shelters out of the city proper. This will improve the disease/sanitation problem of homeless living in the subway, for example. 2. Collect accurate data. Do this by finger-printing at food banks and other measures. Accurate data on the role of drugs+schizophrenia is important. 3. Solicit experimental ideas. Could these homeless people be farm hands? Would they want to? Could you create a digital trash-can that pays rewards to homeless who actively clean?
