The history of slavery directly fed into racism and discrimination post-abolition into ways that minorities without a past as slaves haven't had to experience.
Not only that, but these persons didn't even have a state culture of their own (being owned things and not people, and being forcibly abducted from their own cultures). They had to inhabit a dominant culture created by the norms of others (their owners) and run by them. Their culture was half-adopted from their masters, staff they managed to save from their old countries, and whatever they improvised (under the stern eyes of the whites) here.
Besides, 150 years is nothing in historical terms as it relates to the continued impact of something on a population, doubly so for something as impactful as being see (and having to live as) "an inferior class of persons owned by other people".
For example the US was founded by religious zealots, and even today, 300+ years later and tons of immigrants from others countries having been added, it very much shows, and is very much a dominant part of the cultural landscape.
This is also ignoring the fact that slavery does still exist in the prison system. Prisoners are paid almost nothing for their labour, and are charged astronomical prices for essentials such as toothpaste or deodorant.
EDIT - I would also like to point out that a fundamental point of this article was that the economist discovered it was basically more fair and easier to escape poverty prior to 1970.

African culture and family structure was systematically wiped out, while Europeans didn't face the same struggle. Jim Crow only ended 60 years ago

Take a look at the black-white wealth gap. To root that gap in an explanation other than the legacy of prejudice and slavery is going to require some tenuous logic.
