Nigerians today have to deal with the legacy of colonialism, war, pogroms and famine. (1)

https://en.wikipedia.org/wiki/Nigerian_Civil_War "The Nigerian Civil War (also known as the Biafran War and the Nigerian-Biafran War) ... between 500,000 and 3 million Biafran civilians died of starvation."

This is just scratching the surface.

I didn't mean to minimize any of that. There's no global ordering here.

You stated that American blacks had to deal with the legacy of slavery that happened more than a century ago. The epicenter of modern day slavery is Africa, with Africans enslaving other Africans. In 2018, about 62% of the African population endured some from of slavery.

If immigrants from Africa do better than native blacks, it isn't due to the legacy of slavery. Jamaicans, Dominicans, and Haitians have endured the legacy of slavery too, yet these immigrants do better economically as well. If systematic racism was real, it would hold back all blacks.
