I’d say generalizing that slavery limiting “opportunities” is quite the generalization.
And I understand the need to consider presentism.
I’m pretty confident that writing chattel slavery impaired the liberty of people is a valid statement both in the 1800’s and the 2000’s.
Very good, and welcome back.
A thinking exercise. Imagine yourself in 1850 as a 16 year old, living on a large farm, working as a harvester during crop season. What options do you have for a fulfilling life?
