Not too long ago I got in a cab in New York with a Ghanaian taxi driver named Kwame. He remembered picking me up several years ago. What a memory he has. Anyway, he told me he has four children: one is a doctor and the two youngest are in private school. He said his kids were doing exceptionally well, and he is paying for elite schooling from his taxi driver salary.
