Historical impact of slavery is an interesting topic of discussion.  The book "Why Nations Fail" by Daron Acemoglu and James Robinson posited that extractive institutions such as slavery created cultural norms that had historical impacts.  The map below presents information from the 1860 US Census showing slave population in Mississippi.  The higher the population of slaves the darker the map on the left.  This is compared to poverty levels as measured by the 2010 Census.  The darker green areas have the higher poverty levels.
