I can remember last year and a day out in Birmingham at Christmas there was a 'Homeless' guy outside the station, with a cloth on the floor collecting money, he was all wrapped up in blankets, was unkempt...etc..
I went back into the station and bought him a coffee and a sandwich and gave them to him. He wasn't that appreciative of my generosity and asked me for the money for them instead, so I kept them myself, and walked off without giving him anything.
He was clearly just scamming for money and a coffee and a sandwich would have cramped his begging style..
Annoying, as there are genuine homeless people, I was once one of them when I was a child, and this sort of thing just puts all people off.
Any system will ALWAYS have people scamming it. The basic nature of humanity is to be a greedy asshole.
That doesn't mean you let them rot because That One Dude isn't actually homeless.
And honestly, even the beggars who aren't homeless and are just doing it because it's a low-effort way to get enough money to get by (although I'd hate to see the hourly breakdown in most cases) are being more honest about it than some of the lazy leeches I've worked with before.

To be quite honest, either the folks I told about really needed the lunch I bought them or they didn't. If the first, then I was happy to help. If I didn't, then I still made someone's day a little better. It's not like the cost of an extra pizza and 2-liter would break me, and if they weren't actually hungry, then based on their tears and thanks when I did that, they need an agent in Hollywood STAT.
Also, remember, this is Flint, and they were begging in a run-down, moderate crime area I travel through every day. They do NOT make a lot of money. From what I've seen, they'd be lucky to make more than $20 in any given day.
I guess the reason homelessness and poverty bother me like they do is because I grew up in a poverty-stricken family in the middle of an affluent neighborhood. I saw both the struggle just to survive and the way the neighbors turned up their noses at us for daring to be poor, claiming, like Steve and Blade like to, that we 'chose' to be poor. (My father did NOT choose to have his highly successful store stolen by his partner at gunpoint, nor did he choose to have the restaurant he opened afterward go under because of a multiple-year tourism crash. In 1975, his personal income was almost a half million per year thanks to owning a supermarket. In 1978, he was a security guard making minimum wage.) Hell, I've even been homeless myself on two different occasion.
So yeah, now that I'm NOT living in poverty or even remotely close, I am damned well going to turn around and do whatever it takes to reduce (or even, perhaps, someday END) it. No one should have to listen to their children scream due to hunger.
NO ONE
