The question is whether equal opportunities exist on a population level across races.
And the answer is yes, because those who apply themselves, those with motivation and intelligence, they will succeed, while those who do not apply themselves, those who are unmotivated and not intelligent, they won't succeed.

I'm not pretending racial prejudism doesn't exist, but there are laws in place to punish those who are prejudiced. So on a poulation level, yes equal opportunity exists.

If you believe they do, then there must be some other reason why whites as a group are better off than blacks.
Identity politics. If you are a person of influence, if you keep telling a demographic they are oppressed and disadvantaged, they might start to believe it, and instead of working hard to improve their lives, they cry victim and demand state action to improve their lives for them.

Once those reasons are identified they can be addressed.
Stop telling people in a democratic nation with laws in place to protect people from discrimination that they are oppressed, and instead tell people that hard work and motivation are all that's needed to succeed.

It's illegal to imprison people based on the colour of their skin too, but it seems to be happening if you look at incarceration rates.
Black people commit more crimes than white people, per capita.

Are you more or less likely to succeed if your dad is in jail?
Less. Whose fault is that? The state? White people? Or Dad?

So more is needed than just having laws.
Indeed. We need responsible politicians.
