There's poverty where you grow up on one box of macaroni and cheese per day and your parents are never home but you have a roof over your head and at least free school lunches. You're not actually dying or being exploited into human impotence. You just lack avenues to grow into a full and complete person who can escape poverty.
And then there's poverty once that same child grows up and the welfare system has been dismantled and there's no more public housing, so he/she is working two or three jobs just to afford a roof over their head, real food of any kind is unheard-of, and you'd kill for a good night's sleep or just one Sabbath meal -- if you had the energy to kill.
The latter kind, you can solve just by giving people money. At the very least, it raises them up to the former kind, and from there, all you might need to really improve their life might be a decent library or a community center or a good source of stable jobs.
There's no excuse for not contributing.
