There was a period of US history where a particular region of the country was primarily (although certainly not singularly, and certainly not to the extent 1619 chaplains would have you believe) resourced through slave labor, specifically plantation style slavery which indeed was formed in this region, yes, but that is much more nuanced discussion and tosses out this whole grandiose vision of America being a big power struggle between white men cracking whips at black people.

Btw not sure who is flagging you for asking an honest question. This is how people learn and refine their thinking.
