Step-by-step explanation:
Fredrick Douglass noted several differences between people in the North and the South, particularly black and white individuals. In terms of economic opportunities, the North provided more opportunities for both blacks and whites, which allowed for greater self-sufficiency. However, Douglass observed that there was more racial equality in the South, with fewer instances of racial discrimination compared to the North. Access to education was generally better in the North, leading to higher literacy rates among black people. Moreover, slavery was more deeply entrenched in the South, with a larger number of enslaved black individuals, whereas the North had fewer instances of slavery.
