Yes, Thomas Sowell has discussed this idea extensively in his works, particularly in *Black Rednecks and White Liberals*. He argues that many elements of "black ghetto" culture, such as certain speech patterns, attitudes toward education, and norms of violence, have historical roots not in African culture but in the "cracker" or "redneck" culture from the borderlands of England and Scotland.

These Scotch-Irish settlers brought a rough, clannish, and combative culture to the American South. Sowell posits that black Americans living alongside these groups for generations adopted some of these cultural traits, which persisted even after the Civil War and migration to Northern cities.

This theory is debated, with critics questioning the extent of such cultural transmission and how socio-economic, historical, and systemic factors have influenced black American culture independently. Nonetheless, it's a provocative and well-researched argument that challenges conventional narratives.
