Even the teachers prosper, according to the NY Times:
...a crucial fact about the teaching profession in Westchester County: Teacher pay levels in Scarsdale, and several other districts in the county, are now high enough to constitute an entry ticket to upper-middle-class income and status. In Scarsdale, 166 teachers - nearly half - have base salaries exceeding $100,000; for more than a dozen, base pay tops $120,000.
A study of teacher salaries across New York State found that as administrators and affluent parents compete to give their children every possible advantage, thousands of teachers in the New York suburbs now make six-figure salaries - numbers strongly at variance with the popular stereotype of the poorly paid, altruistic mentor of the young.
