Over the last 20 years, America’s population of college-age Asian Americans has roughly doubled; but during this same period, the number admitted to Harvard and most other Ivy League schools has held steady or even declined, despite significant improvement in Asian academic performance. Furthermore, the Asian percentages at all Ivy League schools have recently converged to a very narrow range and remained static over time, which seems quite suspicious.
Meanwhile, the Californian Institute of Technology (Caltech) follows a highly selective but strictly race-neutral admissions policy, and its enrollment of Asian Americans has grown almost exactly in line with the growth of the Asian-American population.
The stark difference between these two admissions policies is evident in this graph of comparative enrollment:
Top officials at Harvard, Yale, and Princeton today strenuously deny the existence of Asian-American quotas, but their predecessors had similarly denied the existence of Jewish quotas in the 1920s, now universally acknowledged to have existed. In fact, the large growth in the Asian-American population means that the fraction attending Harvard has fallen by more than 50 percent since the early 1990s, a decline considerably greater than the decline Jews experienced after the implementation of secret quotas in 1925.
This reminds me of a friend of mine who was taking the GMAT, she scored a 720 (out of 800) and was despondent. She said "I'm South Asian, there is no way a good B-school will take me with that score!" In order to avoid being racist, the Ivy League has become horribly racist, punishing hard working kids for the color of their skin.
