We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
It is a complicated topic. Private schools can and should accept whoever the heck they want for whatever reasons they want. However relevant SAT scores and grades are, they are not the only things of interest to colleges and not the only measures of merit or of potential. If all a school cares about is IQ, then a combined SAT is an excellent proxy for that.
Anyone who has spent time with these kids notices that they work hard, study hard, are not very creative or articulate. I can well understand why upper-tier schools are not wildly excited to admit large numbers. Vietnamese, Cambodian, Thai and Laotian kids are often more risk-taking and creative, but Chinese students tend to depend on rote learning. Not all Asian-Americans are the same.
Many accomplished people are not all that creative or articulate. In my experience, the emotional damage that 'tiger parenting' can be long-lasting and severe, and only the psychologically sturdiest emerge relatively intact.
These people are a nightmare to work with: among the people I have worked with, a large proportion of Asian descent have issues with authority (they unthinkingly, slavishly obey it), creativity, and self awareness. Too many people like this will simply ruin a school...but you still can't say "no Asians" because that also cuts out people who haven't been emotionally abused. How about "emotionally self-regulating, self-aware folks who are aware of and interact with other people required".
