The fact that it is so difficult for Asian Americans to get into top colleges is a bit iffy, but it is not African-Americans who are being admitted at their expense. It is white kids whose parents are donors or who are legacy. If such practices occurred at the top British universities there would be widespread outrage. This is the negative side of having a large number of private universities; in the UK virtually all are public.
I mean, from what I understand no countries in Europe really have anything like affirmative action right? (And thankfully)
Finland has affirmative action for Swedish speakers iirc; there are also a fair amount of pro-women AA schemes, especially in the Nordic countries.
