Seems like false equivalence to me. A better comparison would be American blacks who immigrated to Canada or Europe.

Perhaps you can imagine the benefit of a fresh start. Instead, American blacks have had a long continuation from slavery.

Consider a financial metaphor -

American whites: compound interest

American blacks: compound debt

American immigrants: reset (bankruptcy if poor)

It is easy to continue momentum, hard to dig out of a hole, and nice to start over.
