Question

who benefited from slave trade why America need slaves​

Answer 1

Explanation:

The argument has often been used to diminish the scale of slavery, reducing it to a crime committed by a few Southern planters, one that did not touch the rest of the United States. Slavery, the argument goes, was an inefficient system, and the labor of the enslaved was considered less productive than that of a free worker being paid a wage. The use of enslaved labor has been presented as premodern, a practice that had no ties to the capitalism that allowed America to become — and remain — a leading global economy.
