I worked for a short time doing door-to-door solicitations for charity. The people in struggling neighborhoods were always more generous than people in rich neighborhoods. Mostly, just like no question, "oh yeah that sucks here's $20 if you're gonna use it to make things better, that's worth it to me." It's like when you get money you start to lose touch with what matters and what doesn't.
My brother said the same thing when he worked for a non-profit that helped poor people with work on their homes. They'd open their homes, give him a meal to show their thankfulness, bring him bottles of water and snacks.
Then later he started doing the same kind of work, but at a for-profit business that had well-off clients. They were demanding and rude and looked at him like he was a piece of trash. He didn't stay working there long because of how awful the clients were.
That's one reason that as much as I struggle, I'm thankful to live where I do, with the people in my neighborhood. Sure, we might have some addiction problems here and even an occasional break-in, but I'd take these folks any day over living in some rich place where people hate each other.
That's me except that I'm not in a poor neighborhood (firmly lower middle to regular middle class).
I've been poor, I've been hungry. Now that I'm not broke, I donate to causes and I buy food for anyone begging outside a grocery/convenience store. No one should be hungry for more than a few hours. No one should have to worry if they can buy diapers for their baby or food for their pet.
