There is no discussion of wealth in your quote. And further, that quote supports what I've been saying.

It specifically says "the cause of this riot was not Tulsa", and "It might have happened anywhere". If it "might have happened anywhere", it therefore has nothing to do with the unique high-wealth of this area.

Takes a lot of cognitive dissonance to unironically suggest that the axiomatic Southern racist belief that "the Negro" should regard "the white man as his benefactor" has no links to their relative wealth.

When you find yourself drawing parallels between your own arguments and those of contemporary white supremacists asserting that the attitudes of local whites were not at all to blame, it's perhaps a good idea to reconsider...
