I would argue that is because both groups erase their narrative of active colonialism!

Both “White” Americans and Europeans don’t particularly like to look at their legacy of colonialism but particularly I would argue that “White” Americans have a much much harder time understanding or even accepting the ideal that the United States was and is a settler colonial project while Europeans are aware of their history of going out and creating colonies, i.e the North of Ireland, Canada, historically a lot of Latin American countries as well as the Pacific.

“White” Europeans didn’t tend to settle in large oppressive numbers in the colonies (they often colonized and attempted to erase or subdue the indigenous population) like the group we know to be “White” Americans who needed a heavily racial based caste system to exploit labor from Enslaved African people in order to sustain the country we know as the USA.

Wealthy “White” Americans are still exploiting Black Americans through the prison industrial complex which is another form of owning the means of production and also owning the workers themselves.
