i’m not sure. if trade laws had been changed allowing export of raw cotton instead of only finished goods, and if plantation owners could have made a profit that would sustain employment over slavery it may have turned the tide. it would have been a slow process, but it may have been enough that good people would have seen a way to survive without it. oh, i know, people will still say the wages would have been meager, but i don’t see a lot of difference between that and the industrial sweat shops that gave rise to the union movement.
