From former New York City schools chancellor Joel Klein, in the latest edition of The Atlantic: In short, politicians-especially Democratic politicians-generally do what the unions want. And the unions, in turn, are very clear about what that is. They want, first, happy members, so that those who run the unions get reelected; and, second, more members, so their power, money, and influence grow. As Albert Shanker, the late, iconic head of the UFT, once pointedly put it, "When schoolchildren start paying union dues, that's when I'll start representing the interests of schoolchildren."
