This is done to every immigrant group, but generally most immigrant waves assimilate and are treated more or less equally. Through all those waves Black people were consistently and persistently treated badly, with things like official segregation, anti miscegenation laws, voting restrictions, redlining, and other unofficial policies and extra-judicial public murders. Not sure what country you’re in but the fact of a permanent visible racial/ethnic underclass that has only recently won the right to vote among other things creates that dynamic.
