Answer: The lack of infrastructure in the South hindered the spread of factories, reinforcing slavery-based plantation work.
Step-by-step explanation:
The lack of industrial capacity in the South resulted in the formation of plantation fields that were mostly operated by slave populations from Africa.
The South did not have a large population, and the climate itself was favourable for the development of subtropical plants. Therefore, cotton exports (mainly to Europe) were the primary income of the countries in the South.
