This is a very sad aspect of life. In Venezuela a lot of women have to prostitute themselves in order to survive. I don't think there's an easy solution. Many homeless people are mentally ill and unable to sustain jobs. If they don't have families able and willing to care for them, their situation is dire. Part of the solution will need to involve institutions that can provide care for the mentally ill. The homeless also include drug addicts. I'm not sure prison is the answer for dealing with that, and it seems an increasing part of the country is in favor of legalizing marijuana and ending the war on drugs.

There are also a substantial number of people who are homeless because they lost their jobs. Those are the ones who would be able to engage in gainful employment if jobs were available. Blue collar jobs and jobs that provide a living wage are becoming increasingly hard to find and that trend will only continue. I saw in interview with Mark Cuban recently, and he said it may be eventually necessary for the country to offer "make work" jobs to offer citizens gainful employment as a way of preventing rioting and social unrest. His Libertarian tendencies are opposed to that, but he believes providing those kinds of jobs is the better alternative. I would prefer providing those kinds of jobs to UBI.
