To add on to Tim’s point about the continuation of racism, the economic conditions that many systemically oppressed black people found themselves in are inherited today as well.
Thomas Sowell proves your stated position is devoid of substance.
Lifestyle choice is not systemic.
You are correct, but we are not talking about "lifestyle choices". Because of Jim Crow laws, it wasn't their choice to live in impoverished locations, with low resources. It wasn't their choice to be forced to accepting low-paying, low-class jobs. It wasn't their choice that dealing drugs and prostitution was the most sustainable way to live - yes it was their choice to participate, but it was not their choice that it was the most profitable way to survive.
In fact, if you study inner-city marginalization, you find that many drug dealers attempted to get out of that business and "go legit". Struggling to survive on a legit income is much harder if you are black, poor, and marginalized. <- none of those things are anyone's choice.
So, I'm not sure why you call these "lifestyle choices" because nobody chooses their skin color, nobody chooses where there they are born, and nobody chooses what socio-economic class they are born into.
All Rama is saying is that a lot of this is still true today - Jim Crow laws disappeared, but that didn't automatically make anyone's lives better, or matter more.
