Of course that's a tragedy, although I'm not sure you're pointing at the right people. The mobs are very often funded by bigger interests. Who stood to lose if black wall street succeeds? It's not the white people of Tulsa. Someone was lying to them to divide them.
The answer to so-called white racism though is always more racism and incompetence. Look at Zimbabwe. The overthrow of stable Rhodesia brought in corruption, theft and societal breakdown.
