Fair enough. My ancestors got here in the mid-1600's, and founded a town called Middletown, Connecticut. According to a book chronicling our history, my family owned anywhere between 25 and 50 slaves until the practice was outlawed (relatively early up north). I can only assume that somewhere there is a child still suffering from this, and that makes me feel guilty whether it should or not.
Your father's story is an inspiring one, and one that is relatively common among the hearty people of Buffalo. And yes, I suppose it shoots down my theory to a certain extent. The fact remains that no single ethnic group was at a greater disadvantage than the freedmen. I can't say for sure why they haven't recovered as a group.
