Most of these street people, I would guess, don't WANT any help from the government, because it comes with conditions. They just want free food, the opportunity to beg money to buy booze and drugs, and a park to sleep in.
I think the only "assistance" most would be interested in is a monthly wad of cash over the counter with no questions asked, and you know what it would get spent on.
Poverty is understandable, in our capitalist economy, but letting yourself go to the level of an animal? That I can't understand. Even cats bury their poop, why can't a human?
