Half way through listening to this guy it's clear he believe in some inherence to white people being inventors while black people aren't. It isn't scientific, he just thinks black people are incapable of doing certain things and just need to stop complaining. He's not even criticizing "FBA" specifically, dude said Nigerians, Benin, Ghanaians, Jamaicans, and Haitians have no culture.
Though he does touch upon this when asked at some point by saying when he was young they loved African Americans because they knew WEB dubois and lots of African singers. His generation only had contempt for African Americans when they came to America not before. So he says he sees too much of Africans in African Americans insofar as violence, meanness, dishonesty, and anger. Compares this with what AA's say about "Crabs in a bucket" mentality. He mentions his first wife was African American.
Essentially, he has this incredibly macro view of black people where he thinks we're all relatively the same regardless of where we are. That we're poor and can't build because we're communal and not individualistic like whites, jews, and Japanese. So he doesn't really care about specific history of individual group of people. He just thinks other races can do certain things and blacks can't. He went on about how historically Africa is just easy to live not dangerous, and has everything so Africans didn't have to think or be inventive.
It's essentially a super conservative, ethnocentric, biologically deterministic, and homogenous view of the world.
The other guy is friends with frank and is giving him specific reasons why this might be the case for AA but Frank clearly doesn't think the why matters. He's more interested in the now, but oddly, Frank doesn't even think it's possible for black people as a whole to do anything about any of this. He just thinks this is how black people are.
