Not much difference in the end of course, and still a major societal issue. But a different one.
Greenwood was a prosperous black area near Tulsa, doing so well that it was known as "Black Wall Street". White resentment eventually boiled over and 35 blocks were burned to the ground. Hundreds were killed, and it included many horrors, including white people using then-new airplanes to firebomb the neighborhood from above.
If you read Loewen's "Sundown Towns" you can find plenty more incidents where white resentment of black success led to oppression, violence, and sometimes death.
E.g. I'm naturally gregarious, will chat up folks in line at the gas station buying a Coke etc. I noticed one day I didn't chat up anybody that didn't look like me. So I started.
When my friend visited me in Silicon Valley he told me it's not that diverse -- at least not in the way we would want diversity to work. He told me that next time I go out to eat, I should look through the windows of all the nice restaurants I walk by and see who the customers are and who the workers are. My friend is right. There are under and upper classes in SV and it's often clustered by race. I never noticed because I'm Asian and I'm in the group that benefited.
