What was Hinton Helper's view expressed in "Impending Crisis of the South"?

Hinton Helper's view in "Impending Crisis of the South" argued that non-slave owning whites were among the most disadvantaged by the institution of slavery. Helper contended that slavery primarily benefited the wealthy plantation owners, while the majority of the white population, who did not own slaves, faced economic and social challenges due to the establishment of a society that prioritized the interests of a small elite. He believed that the system of slavery suppressed economic opportunities for these non-slave owners, leading to broader issues of poverty and lack of upward mobility in the South. This perspective was quite significant as it offered a criticism of slavery from a non-abolitionist viewpoint, focusing on the detrimental effects of the institution on the white poor in the South.
