Not the time or the place, but I've been drinking and I've been reading Oxford's "Battle Cry of Freedom", about the American Civil War, so I'll take a moment to pontificate on slavery. Slavery is wrong. Not for moral or ethical purposes. It just fails economically. The Civil War proves this to a degree, but basically, it makes more sense to pay someone to do work for you and then stop paying them when they aren't useful to you than to buy someone to make work for you. Because if you own a person, they'll work as little as they can to avoid a whipping while a paid person will work hard enough to keep from getting fired. And after a slave gets too old to be useful they didn't just take them back behind the woodshed and shoot them. You've got to provide for these slaves until they die
On top of it all, it perverted the economy in the South. In the South, the goal was to work at something until you had enough money to buy some land and some slaves to work it. In the North you worked until you had enough money to build a factory and hire some workers. So the North got industry and commerce and the South got acres and acres of fields and slaves you had to feed and house and maintain.
