The new Thomas Sowell book

Black Rednecks and White Liberals, here is one summary by Sowell:

The culture of the people who were called "rednecks" and "crackers" before they ever got on the boats to cross the Atlantic was a culture that produced far lower levels of intellectual and economic achievement, as well as far higher levels of violence and sexual promiscuity. That culture had its own way of talking, not only in the pronunciation of particular words but also in a loud, dramatic style of oratory with vivid imagery, repetitive phrases and repetitive cadences.
