Hmm interesting reference to black wall street, however wasn't this community the exception to the rule? Where not most minority communities economically disadvantaged?
As far as Marcus Harvey is concerned his political beliefs where actually closely allied with the KKK. He in fact says so himself.
"Garvey recognized the influence of the Ku Klux Klan and, after the Black Star Line was closed, sought to engage the South in his activism, since the UNIA now lacked a specific program. In early 1922, he went to Atlanta for a conference with KKK imperial giant Edward Young Clarke, seeking to advance his organization in the South. Garvey made a number of incendiary speeches in the months leading up to that meeting; in some, he thanked the whites for Jim Crow.[34] Garvey once stated: "I regard the Klan, the Anglo-Saxon clubs and White American societies, as far as the Negro is concerned, as better friends of the race than all other groups of hypocritical whites put together. I like honesty and fair play. You may call me a Klansman if you will, but, potentially, every white man is a Klansman as far as the Negro in competition with whites socially, economically and politically is concerned, and there is no use lying."[24]"
