Wrong about New Jersey. They still had slavery all during the Civil War. And when it came time for NJ to vote for ratification of the 13th Amendment...they voted NO.
NJ only had a small number of slaves but they sure as hell did not want to free them. Somewhere along the way they changed the name of their slaves to "servants for life". Made them feel better.
Yes I believe it was 16 slaves wasn't it that the 13th amendment freed in New Jersey. 4 million in the slave states. Good point. Doesn't show how those 16 were in any way the equal to the nearly 4 million in the South in terms of financial gain which is the point you are trying to make.
