Fact of 1861
"All aspects of commerce will collapse, from iron and steel to woolens, clothing, and garment manufacturing; every shopkeeper will close his doors, as all kinds of goods from Britain and France will flood Northern markets. The whole country will be given up to an immense system of smuggling."
This was common talk of Spring of 1861. It shows that it was common knowledge that Northern products were artifically inflated and priced higher than imports. It shows that Southern consumers prefered European products. It shows that high tariffs were supporting the entire North. It shows that the "highly successful Northern manufacturing" network was being subsidized by the government laws, and the government being subsidized by taxes on slave labor products. Any moral superiority there?
