Also, remember that the disabled guys standing (or sitting) out there are almost definitely getting a disability check...especially vets. Not to mention free housing, medical benefits, and food stamps. .
This is just not true. If you get SSI then you are immediately cut off of food stamps, at least in CA. And you don't get free housing either. Bums may get cheap government subsidized housing but they will never have more than a few hundred a month to live on after rent is paid. As for whether people spend their money on alcohol, why does that matter? Even though it's really unhealthy, alcohol is sometimes the only thing that keeps someone's brain chemistry stabilized enough to function on a basic level. I used to smoke weed every day to deal with depression and, honestly, I was a lot easier to be around high than when I was sober. I'm not currently using at anywhere near that level, but only because of years of experimenting with finding the right food and supplements in order to wean myself off it. So I'm not going to judge someone who is just trying to survive without being miserable, especially if they're poor and uneducated about holistic health. Most people just tell bums to get on the right psych meds but how is that any better? Those drugs typically cause a lot more cognitive damage than alcohol does, as well as diabetes, high blood pressure and all kind of other problems. Psych drugs also shut off the creative process entirely so forget about it if you're an artist. Veterans, particularly, need something to cope with trauma issues, and so does virtually anyone else who has lived outside with no other options for any length of time. Also, not everyone asking for money spends it on drugs. For the last couple years I was traveling I spent all the money people gave me almost exclusively on either food or basic gear like good shoes or a sleeping bag.
One idea that has been really useful for me in thinking about these issues is that right brained people are, according to numerous studies, more likely to end up in jail, psych wards and homeless shelters. This is because of their having chaotic neural patterns that make it hard for them to function in highly structured environments that emphasize left brain, analytic logic. What's interesting is that right brain dominance is also typically found in artists as well as some risk-taking scientists. So, I think what this indicates is that our society is structured incorrectly, so that huge numbers of right brained people, who account for about 10% of the population, will inevitably end up living in hardship and poverty. Why is it that indigenous cultures never had what people now would think of as "homelessness"? Probably because their communities allowed for enough deviation in cultural standards that creative thinkers could find their niche. What is necessary is finding a way to recreate those cultural niches instead of trying to blame people who are already living in difficult circumstances. The closest I've ever seen to a cultural system that could allow for autonomous, creative thought is permaculture but that's a whole other subject.
