Slavery, abolished 150 years ago, measurably influences who is rich and poor today (see abstract below), and even who we vote for. It is one thing to say in a general sense that we are living with the echoes of slavery. It is quite another to control for all other variables and find that current inequality correlates with slave concentrations eight generations ago. We're not as independent as we like to believe. We can't escape the past. We must either face it as best we can, or let our ignorance compound its ravages.
