The section on plows is essentially correct. Given the artifically higher price of a foreign import, an American manufacturer would be able to price his product higher that he could have otherwise. However, the sample price of a plow is far too high. More importantly, a citizen in a slave state would not be forced to make a choice between Northern manufacture and a foreign import. Most common farm tools could be manufactured and repaired locally. The same is true for common plantation machinery, such as the cotton gin. We are also ignoring the durable nature of most tools, which meant that suitable implements could be purchased at estate sales and moving sales, which took place frequently.
