What was NOT a socioeconomic class of the south in the middle of the 19Th century?

In the middle of the 19th century, the primary socioeconomic classes in the South included wealthy plantation owners, yeoman farmers, poor whites, and enslaved people. However, a distinct middle class, as understood in modern terms, was not well-established in the South at that time. The region's economy was largely dominated by agriculture and slavery, which limited the emergence of a robust middle class. Additionally, there were few urban centers that could foster a diverse range of professions typical of a middle class.
