band on the run,
Southern slavery was monumentally vile, criminal, and any other ( inadequate) descriptor we can find.
But the value of the OP is not in making point for point parallels between the two. But the comparison dramatises a critical truth: people who long accept a institution that regards slaves and masters as a holy arrangement from god destroy the inner man long before the slave dies.
Also, a slave that feels they have intrinsic value is a threat to that system. A person who desires to exercise their free will cannot long survive slavery-- any who deny that the slavery structure can be maintained except through the most coercive means is deluded. The penalties must be severe. To accept the premises that underpin the operation of a master slave relationship corrupts not only the mind of the master, but of the slave as well. It's a living death of a person.
It reminds me of women who are subjected to powerful and long term verbal/psychological abuse who say they might have left sooner if their men had simply beat them--but their minds and self concept had been so distorted that they had no power to leave--so they thought--and so it was true.
As a side note: I am always glad when there is outrage that anything can be compared to slavery--Too often I have been around people who shrug slavery off as though it is no big deal--times being tough, wasn't it fine to have food and covering? etc...
Also--we are comparing U.S. style slavery. There were customs for slaves in various cultures that were not identical to the mode of work and status that existed here. Slavery in ancient Israel (if we can believe that jubilee years were observed) granted more than monetary value to the slave/servant.
ps. Did I mention that I hate the WTBTS?
