That's how it was when I graduated Dalton in the late 80's. We had 60 out of 110 graduate to Ivy league colleges. Great academics, creepy spoiled kids. it's a trade off. Personally I hold a lot more respect for my 1-9 school, Allen-Stevenson with it's dress code, and non PC environment.
I went to Ramaz and then to Buckley. I got accepted to Dalton and Collegiate for High School. While I hada great time visiting Dalton, it was not for me.
As for Political Correctness, virtually all of the schools have been infected. There is a special counsilor for gay students at Collegiate now. In my day (1992-95!) kids stayed in the closet until the last semester of senior year.
We aqre dealing with an all boys school. The last thing we wanted was a gay clique. Unfortunately, a new headmaster was brought in and decided to change the climate and mores of the school.
