That's probably spot-on, yeah. You can't solve social injustice and people suffering _forever_, no matter how much money you donate. You can make sure to get this building fixed with donations, though.
I'd still question my priorities when I'm handing over a check worth $200m.
Or at least I'd like to think I would. Who knows how fucked your perception of money & worth is once you enter those stratospheres of wealth.
