Exactly, there's a sick, twisted sort of truth in there, but dude is forgetting the slavery side, the no freedom side. He can go into slavery himself if he thinks it's such a great way to learn lucrative new skills.
The point of the claim is to diminish the horrors of slavery and to eliminate it as a factor in the current poverty, lack of education, and crime that endemic in black communities.
Once they do that they can just say it’s a “race” thing, and re-employ racist policies to put black people in their “proper place”, whether it be one of servitude, subjugation, or exile depends on the flavor of bigot.
