Keeping slaves would have held our entire economy back in the first place. We wouldn't have freedom, and would still have unreasonable murders on slaves themselves. We also would have more stuck-up and snotty upper-class people than today, that push people that are lower in class than them around, and think of the suicide rates because of this bullying. Slaves should not have been a thing EVER, it was just a way for higher classed people to sit there and force people to work for them with little to no pay, while they do less work and make much more than them.
look past the bad things that happened when the slaves were existent there were a lot of things the slaves did for the country like they helped us have food and have supplies for what we needed like cotton farm crops in general they boosted the production of the economy in general the slave time period may have been bad but were not arguing if it was bad were arguing that if we kept slaves today we would have a better and more boosted and up to date economy today and showed during the south the more slaves that worked the more things that can better there area like cotton and corn and cloth and guns and have that time period more futuristic then what the time period is then that is why and how the slaves would have bettered the economy.
