It is through the cotton gin that many historians believe slavery would have quietly run its course. Many historians argue that
The South was desperate for a new crop to sustain their economy as they had largely shied away from industrialization. The argument that someone else would likely have invented the updated cotton gin allows for the rejuvenation of slavery and the renewed dependence on slave labor and a cash crop.
