"I think Garvey's downfall was trying to establish a black socio-economic nation within a white supremacist nation. "......

i don't think it was his "downfall" (this was one of the things that made the Rt. Hon. Marcus so great) but i overstand what you are saying and you are absolutely right. White Supremacist destruction of things such as Black Wall Street and the slander of such individuals as Rt. Hon. Marcus were because African people were too successfull for this White Supremacist society, not because they were corrupt or unsuccessful, and their actions/responses to these things make that plain to see. if someone was failing in there attempts then one could let them be and they would bring about their own downfall. However, "the System" knew that organizations such as these would be strong enough to destroy the white supremacists domination of non-white people.
