It's really hard to move beyond the survival state when your forefathers spent over 100 years living as slaves, almost 100 years trying to gain full citizenship living in a de facto apartheid state and then being asked to somehow enter society as though 200+ years of white racism just didn't exist.
I honestly think they are taking the hostilities rather well.
Slavery has been over in the USA, not Africa, for 150 years. Slavery was an equal opportunity system. There were white slaves, black slaves, and native Indian slaves. There were also black slave owners, white slave owners, and native Indian slave owners. That's the story of human history, before the industrial revolution, that eliminated the need for manual labor, and started putting machines to work, instead of human labor. So slavery, in modern countries became obsolete, and instead of paying for the care and feeding of slaves, labor was allow to compete for jobs, and become wage slaves, earning in many cases, much less than what was required for their care and feeding. Some, of every race, prospered, based on their intelligence and abilities. Many, lacking in quality abilities fell behind economically. They couldn't compete successfully, because of their genetic inferiority. Nothing new under the Sun.
