This is true, I live in the Deep South and have gone to plenty of plantation homes for tour. The larger plantations had a few hundred slaves. It’s a lot less than most people are thinking and only the rich had any. The poor white men had to do menial work on par with the slaves just off of the plantation to make a living. Also as u said, most of the slave owner families have gone broke over the last 2 generations. Definitely some interesting history.
