"One estimate, generated by Laurence Chandy and Brina Seidel of the Brookings Institution, recently calculated that the global poverty gap — meaning how much it would take to get everyone above the poverty line — was just $66 billion. That is roughly what Americans spend on lottery tickets every year, and it is about half of what the world spends on foreign aid." Love this.
I'm really curious about the math on that $66 billion number. According to the world bank there are about 750 million people living in extreme poverty. We only need to give them $88/year to get them out of it? And that's just the people in "extreme poverty." It'll be even less if we move up the income scale a bit. The number seems low to me.
Can't say that explains it all but presumably there are other things like that.
