Yeah think of this almost more as racially enforced endetures servitude and not triangle trade era slavery. And don’t underestimate the power of bureaucracy! This sort of system tends to be highly documented to help prevent people just up a and stealing a slave, and allowing them to do jobs outside of direct oversight of their masters. . Two types of people had direct access and ownership of slaves in this sort of system, the government, the churches, and the wealthy/powerful. 3 things you don’t want to fuck with, steeling a slave in this system is kind of like jacking a mail box, you food do it but why risk the major federal crime?
