• We economists, in our classes, teach students that to some degree, price discrimination is actually a good thing; that it allows you to serve lower-income people. Take Africa, with AIDS. They could never finance what an AIDS cocktail costs here, over $10,000 a year. But if you sold it to them for $300 a year, which just barely covers cost, they could probably serve quite a few of their citizens, with World Bank help. We economists say that will be beneficial. But it's a two-tier system; yes, African people pay less than we would pay.
