There are selection biases when it comes to immigration to the first world that select for things like emphasis on high educational attainment/striver mentality, plus common cultural differences we see with immigrants from all over with respect to the relative strictness of parenting. Recent immigrants from Africa are also not coping with the multigenerational trauma of slavery, Jim Crow, &c., in the way that black Americans generally are.
None of that means that recent Ghanaian-American immigrant families aren't also subject to anti-black racism in the United States in a way that is important, potentially unifiying, formative for their children who grow up experiencing it, etc.
