The slaves were not attached to the land because if their owner decided to move or to sell them the slaves went where their owners sent them. Serfs were not the property of the land owner they were part and parcel with the land.
Many wealthy northerners held slaves as household servants, just what did these people have to do with land?
mheslep,
Indeed Hamilton set up the first national bank, but he did MUCH more then that. As the first Secretary of the Treasury he set up the entire financial basis of the US. The system he set up was practical and theoretically sound, it is still in use. Smith was a primary reference for everything he did. Indeed government hands off was a big piece of it. These policies had to be established by someone sometime, it was Hamilton in the 1790's.
Not clear to me how it can be denied that capitalism was the economic system of the south, wasn't it part of the US? Just because the southerns did not begin creating factories does not mean that they couldn't, just that they didn't, there is a difference. Sure most of the south was agrarian, but even the small land owners held slaves, it was a prestige thing. IF you could afford a slave you got one or two.
What ended slavery? I think Russ said it. Many northerners were offended by it. There were enough wealthy abolitionists that they were able to get some papers printing essays against it. The papers of the day were shooting for emotional responses, they finally were able to stir up enough feelings to drum up support for a war to end it. The northern capitalist did not have to be an abolitionist to support the war. What good capitalist does not love a war?
