> Had he been born in Africa, Hanauer points out — where the potential customers for his entrepreneurial efforts would have barely enough money to survive — Hanauer would likely be selling fruit by the side of the road

Africa in not a country. It's a continent with 50 plus countries, some with a middle class with decent spending power. So there's a high probability that Hanauer would in fact not be likely to be selling fruit by the side of the road growing up in a middle class family (as he did in the US) in an African country.
