And I don’t think it’s different in the US, although our kids can go to school for free, if you don’t count money for clothes.

A NYTimes Op-Ed says:

Two M.I.T. economists, Abhijit Banerjee and Esther Duflo, found that the world’s poor typically spend about 2 percent of their income educating their children, and often larger percentages on alcohol and tobacco: 4 percent in rural Papua New Guinea, 6 percent in Indonesia, 8 percent in Mexico. The indigent also spend significant sums on soft drinks, prostitution and extravagant festivals.

Look, I don’t want to be an unctuous party-pooper. But I’ve seen too many children dying of malaria for want of a bed net that the father tells me is unaffordable, even as he spends larger sums on liquor.
