I agree with this sentiment, for very different reasons. It isn't that people are worth only what they can contribute to Capitalism and that those who cannot contribute enough are less worthy of a family, it's that those are harsh conditions. They aren't suitable for raising children.

But at the same time, the Black population needs to be maintained in order to resist white supremacy and to eventually topple the Capitalist system that forced them into a position as a lower class in the first place.
