Not sure what your point is. Northern textile mill owners profited from cotton grown by slaves. Northern bankers profited loaning money to Southerners to buy more slaves. Shipbuilders in the Baltimore and other Northern ports made money building ships used in the slave trade. Insurance companies in the North made money insuring cotton cargos to New England and Europe.
You don’t suppose that the plantation owners made money from the crops that slaves tended. You don’t suppose that the Southern railroads made money transporting cotton grown by slave. You don’t suppose the ports of Charleston, Savannah, Mobile, and New Orleans profited from the cotton, tobacco, sugar and rice that flowed though their ports. If there was money to be made, people will make it. Called capitalizm, that is the way it worked in the world, in those days.
Bull,
I am not sure what your point is? Mine is of the hypocrisy of the “northeast” in bringing the vast majority of slaves to America and selling for profit. They continued running slaves after Virginian Thomas Jefferson’s Act of 1807 Prohibiting Importation of slaves.
They were the “drug runners” of their time! But slaves instead of drugs.
