First of all I'm too lazy to read your entire post, but I offer you up one counterpoint.

It is much easier to distinguish blacks from whites than Jews from whites. Much of the racism in American history is based on this distinction. I'm not saying blacks can't succeed in business because they look different, but I believe that whites in post bellum America were more likely to identify with people of the same skin color.

I don't know if that made any sense, so if it didn't just forget about it.
