Wow, I'm really not sure how to judge your friend ethically... Providing a source of breast milk is really important. Providing a source of income for people who are poor enough that getting milked for $2 a day sounds good is important. But this is pretty clear exploitation. I think in poorer countries, living costs and incomes in urban areas are lower than in richer countries but not vastly so. However, out in the countryside, especially in areas where the farming is mostly subsistence, currency is hard to come by. When everything is okay, that isn't so important because people can get locally produced food and shelter, but when someone needs medical treatment or just imported building materials it is. However, the people in those areas are not very mobile. There may be a minibus network or similar, but getting to a major urban centre is a big deal, costs a significant amount. You could set up a deal NGO clinics where those exist. I don't know much about Cambodia though personally... But yeah, I don't know if he's doing a good thing or a terrible thing.
