Well since you are not a taxpayer, it seems you don't have a dog in this fight.
We could look at it from the viewpoint of a homeowner or parent. Homeless people using the curb for a toilet, a lawn for a needle disposal and just about anywhere for used condoms, is a breeding ground for disease and a crucible for crime.
Looking at it from the homeless POV, the weakest become victims of crime. The stronger homeless take advantage of the weak and the mentally ill. Rape and intimidation are common amongst the homeless.
If we could conquer our petty ego, we could see to setting up universal income, which is cheaper in the long run and gives people an opportunity to rise above squalor. It is cheaper to house the homeless, it is cheaper to feed the hungry and it is cheaper to care for the ill.
Under universal income, a 'homeless' person could be told to go home, and he'd have a place to go. The signs of beggars willing to "work for food" would be a thing of the past. And a drug addict instead of dying on the streets like a dog, would instead be in a rehab.
We are at the beginning of the collapse of the current financial age. Most labor will be obsolete in a few years. We are witnessing the collapse of retail workers as stores and malls close and warehouses become automated. Transportation automation is only a few years away. When was the last time any of us went inside a bank and cashed a check? A rise in fast food wages promises to bring on automation. We see IBM's Watson taking over the job of doctors in the cancer field (look it up yourself), and many more white-collar jobs will be handled better by software programs.
We will either share full time jobs, or accept a large part of the population is not needed for work.
What do we do with excess? Have them living on the streets and under bridges waiting to foment revolution? Or do we recognize the table of bounty is big enough for all to enjoy?
