Politics isn't about efficiency, compassion or common sense. It's about controlling and thus owning other human beings.

If people actually wanted to solve this problem, it could be solved--and even then rather easily. In the case of NY, they could put up the homeless in foreclosed properties and, as a part of 'free' room and board they could keep up the properties and do other tasks around the city.

As ever this issue is a matter of basic orientation. There are those (usually the political class) who search for the reasons why something won't work, and then there are those (usually the rest of us) who search for things which will.
