Rounding up minorities to work in labour camps is likewise intrinsically abusive. Again, the argument you’re trying to build is based on chattel slavery being excessively abusive the way it was practised in US. This implies that you don’t actually have an issue with the concept in general, just as long as slaves aren’t abused excessively. Hence, US prison system today is not comparable.

I love how you further go on to minimize the scale of the US prison labour system. Entire state economies are now based around it. In the United States today there are more prisoners than farmers.

You keep on digging though.
