the us could have bought out all the slaves and shipped them abroad for 1/100th the price of the civil war, but the whigs didn't want "freed slaves" they wanted a genocide to cement their century of rule.  they tried to start a civil war an entire generation beforehand and it had dick all to do with slavery, they just wanted federal forces to enact mass murder on states that refused the "commands" of the central government.  lincoln was a whig. lincoln literally refused a gift of several free ironclads to extend the war and have more death.
