The comparisions of Slavery in the early days of America, to the WatchTower today are endless
here are just a few that come to mind
1) You have your Overseerers
2) you work for free
3) Slaves were not encouraged to be educated, because just like the GB in brooklyn, knowledge and independant thinking in a slave was considered dangerous. A dumb slave was a safe slave
4) The Elders serve as Slave patrols, miss a couple of meetings, they are at your door to reign you in.
5) Slaves in the early days of this country would be punished by beatings, and if you survived the beatings you could be separated from your family by being sold off. This religion punish you with lies and gossip (beatings) and separates you from your family(disfellowship).
