Answer:
The South benefited by keeping slave labor. The North did not.
Explanation:
The South relied on old money and land and power handed down through generations. The main industry of landowners was extensive arable farming. This required a high volume of manual labor. However, paying labor and fair working condition and equal rights would have reduced the labor and reduced a land owner’s capacity to make a profit. Slaves provided labor. The North developed a free-labor industrial economy. This benefited from manufacturing but also benefited from the employees to be able to spend money and make money for themselves and aid economic growth for the entire country.
