I'm amazed that we are going in circles with this culture of poverty bullshit (which somehow isn't actually framed as cultural because culture is malleable/constantly changing, but the culture discussed seems to presented as natural extension of blacks inferiority) and simple blame on the social structure.
I only frame it in the way these dipshits present it because even if you grant them their lie that racial disparities are a product of "cultural" differences, with some cultures promoting worse decision making than others, the question of "why are there cultural differences" never get answered. That's because they are invoking the "black culture is bad" argument to replace all the very real socioeconomic and legal oppression and violence that you describe.
They reject every possible environmental factor presented that explains these disparities, leaving the only other available option to be genetics. The logical conclusion of their argument is that black people are inherently more prone to violence, being poor, etc. "Black culture" just means "black genetics" in this context.
