Regarding slavery in the US, yeah, prison farms are slavery. The constitution permits slavery explicitly as a punishment for crimes. That's not something I agree with either but that's just straight-up facts. When you use prison labor for private company benefit that's beyond the pail and the US gets criticism for this behavior regularly from the UN ILO. There's no better way to undercut the wages of hard-working Americans than forcing people to work for free. [1]
Where you run off the rails the the idea that people want slavery back. Nobody wants that. The establishment has much more nuanced and effective ways of keeping themselves well-off. IMO they've probably always been after the ends, not the means.

Even if one's ancestors believed in it, it does not mean that you can't have different views and see the wrongness of historical actions. And of course there is plenty of racism around today.
