How were the northern mill system and the southern plantation economically similar

Explanation:

The Southern plantations were connected to the Northern mills because without the Southern plantations, the Northern Factories would have no crop to turn into products. For example, cotton would be picked by the slaves on the Southern plantations, and then be brought up to the Northern factories in order to mass produce such things like clothing. This occurred especially during the time of the Industrial Revolution when factories were becoming more abundant and the deskilling of laborers was rising. Resulting from the Industrial Revolution, many people and immigrants sought factory work, and this also increased the amount of slaves that were needed. Also, such things like the Lowell Mill came about, and the Interchangeable parts flourished.
