Did you know there were about 10,000 black slave owners in the US prior to the US Civil War?
Did you learn real history in school, or political agenda driven mush?
Your school probably never taught you that the only reason slavery was abolished was because Europeans invented carbon fired engines to do the work. slaves became too expensive compared to an engine. If or when the fuels run out, or if the "global warming" idiots win, slavery will be back. They won't ever talk about the economic realities of history.
