The problem is, you want to look at this topic from a viewpoint that doesn't take into account all that has happened in the US.
Black people in the UK can be put into two categories. Those from the Caribbean and those from Africa.
Those from Africa heritage do as well as white British people, or better.
Those from the Caribbean heritage do really badly.
In the 2022 to 2023 school year, pupils from the Chinese ethnic group had the highest Attainment 8 score out of all ethnic groups (65.5 out of 90.0).

The average score in GCSEs (taken at the age of 16) is 46.3 out of 90.
Black people get 46.6 out of 90
Black Africans get 48.7 out of 90
Black Caribbeans get 40.0 out of 90.
White get 45.2 out of 90 with white British getting 44.9 out of 90.
What's the difference between Africa blacks and Caribbean blacks? History. Crime.
The Caribbean blacks were slaves, just like in the US.
African blacks weren't.
Crime in the Caribbean is high. In Africa it depends on the place. But the Yardies and other Jamaican gangs (because Jamaicans didn't need visas to go to the UK back in the 1980s and 1990s) infiltrated the UK and they're still an issue today.
Unless you try and stop these problems, then things will always be this unequal, it impacts kids who grow up in ghettos, who have a mentality that someone is out to get them, that life will be difficult.
The US has tried to do things, but never enough. Trump wants to get rid of these things altogether.
