Not the same as a half caste elite ruler class over a 90% black country, rich off of slavery money invested into businesses around the area.
Similar, but not as powerful or pervasive.
Id say the end product is similar when it comes to how they think and carry themselves. How many of those familes got their wealth is where things begin to differ.
Like many of the Boule/old black money familes in the USA have stories that are respectable and often taught to us to inspire us, but how the descendents of the person who got the initial wealth carry themselves is often very different then their ancestor who sacrificed.
