I traveled around India for about 6 months. I was happy to give initially, but being taken advantage of over and over took a toll. Beggars tried to emotionally exploit my girlfriend, sending their young kids at her to literally grab at her pant legs and make the motion for food. She'd give them money. When we passed by an hour later the same kid would be at my girlfriend again for more. She ended up crying a couple times a month because we didn't have much money, certainly not enough to hand out.
I'm now indifferent to even brutal poverty.
