I've raised two smart kids here, both attending college now, but the schools are like schools everywhere in the tri-state area, whether with or without too much money: great (but not as enriching as home) until about grade three; best of intentions and some fine staff simply cannot buck the system, which is built to churn out, at the very best, more nice little worker bee underinformed voters utterly lacking in critical thinking skills -- and of course at worst, drug addicts without a chance, of which we gots lots.
In other words, whether the school system is populated by the over-privileged or not, it largely is what you make of it. You absolutely canNOT keep too close an eye on their friends, but as long as the interactions at home are interesting and feed their heads, they'll want more of that and try to choose accordingly; the selection isn't as large as some, but it's OK. They'll gain a taste of what street-smarts are, and of why it's good not to need them, and of sympathy for the downtrodden -- all good things. The air is pretty clean and likely to stay so.
Oops. I'd bet this doesn't stay up long; too bad, it should. Oh, well. Cheers
