Assuming we’re talking about America, and not the world…
Many whites had multiple generations established, before the freeing of the slaves (the ancestors of the majority of black Americans.)
A freed slave population had little/no possessions/land, or education. Certainly no political power… Many had to start from scratch, into a world being forced to assimilate with them over time.
Whether you are freed, or born into poverty, it’s a huge disadvantage. Parents in impoverishment work longer hours, for less money, and as a result are not around their offspring as much. So. They have less opportunity to teach/raise their children.
Then there is the school situation, addressed above.
And incarceration rates, due to poverty.
There have been great strides made, in civil coexistence.
Still though, the black community has more disadvantages. Multiple studies have shown that two applicants to a job can have the same credentials, but a name that insinuates a “brown” person is less likely to be considered for the same job. Example. Ladarius Washington, versus Gary Washington. Ladarius is less likely (don’t remember the actual %) to even be considered by some employers, because the applicant is perceived as “black.”.. (side note, look up “white privilege.”)
Whites are more likely to have established wealth, built by generations.
Blacks are more likely to be the first, or second generation of wealth building.
Whites are more likelyto “know the right people.” More likely to have established acquaintances, that can help them navigate/circumvent things that would hinder ordinary people.
Projection of “wealth.”
The two races (white/black) generally, have cultural differences in how many choose to spend their money. At least as far as those who project stereotypes (the “loudest” of both races.) A lot of what I would consider “young black” culture, could be perceived as glorifying a showing off of money i.e. rims, jewelry, shoes, grills, huge bar tabs/parties etc.
(Stuff, I see, as a poverty thing. Think Elvis. He was impoverished growing up, and had trouble getting food. When he became rich, he adorned himself with gold, and essentially ate himself to death…)
The difference between the two races wealth, usually depends on the person’s starting point. With obvious exceptions, and anomalies…
