Because schools withhold a large percentage of their spots for "legacy students", a White kid who isn't rich or well-connected is less likely to get into these elite schools than an Asian kid with the same grades. Half of the White students at Harvard are legacy students [1] and White students make up 44% of the Harvard student body. 50.9% of Gen Z is White [2], meaning that slightly less than 51% of the population is competing for 22% of the slots. The same numbers for Asian students are 5.3% of Gen Z and 25.9% of the spots at Harvard. Now, the proper numbers to use are probably SAT scores or some other "skill metric", but finding the proper stats to use is difficult since College Board locked them down, and in this case the population stats don't affect the conclusion because while more Asians have high scores as a percentage of their group than Whites do, it is canceled out by the difference in population sizes.

Assuming Affirmative Action is still in place, once the current generation of Asian Ivy League grad's kids start applying for schools, this issue will start to apply to Asian kids as well.
