The first is a conservative letter coming to the conclusion that the unions position is not about the kids or the teachers. “It’s all about the money, stupid.”
The second is a somewhat incoherent liberal letter. What does the following sentence mean? “Anyone who works for a salary realizes that such an approach could unfairly victimize himself…” If anyone victimizes himself, who is the oppressor? I’m not sure that Mr. Brenner knows what his “own best interest” is.
