USA HISTORY

Detailed explanation-1: -Southerners claimed that enslaved people were healthier and happier than northern wage workers. Most white northerners viewed blacks as inferior. Northern states severly limited the rights of free African Americans and discouraged or prevented the migration of more.

Detailed explanation-2: -Former slaves would now be classified as “labor, ” and hence the labor stock would rise dramatically, even on a per capita basis. Either way, abolishing slavery made America a much more productive, and hence richer country.

Detailed explanation-3: -The Southern states wanted to assert their authority over the federal government so they could abolish federal laws they didn’t support, especially laws interfering with the South’s right to keep slaves and take them wherever they wished.

Detailed explanation-4: -In general, the conditions of slavery in the northern colonies, where slaves were engaged more in nonagricultural pursuits (such as mining, maritime, and domestic work), were less severe and harsh than in the southern colonies, where most were used on plantations.
