A teacher explains why she's quitting the New York public school system.

How does one keep order without a threat to punish or exclude? You don't. But if the rationale for educating children is equality, how can you exclude them? You don't. So you end up with a system that allows children to threaten teachers. And the teachers, of course, can't be paid enough to take such jobs. The article strongly implies that the only way New York keeps the positions filled is by the ignorance of incoming teachers, who teach a year or two then leave. No wonder we pay so much for public school teachers, and still get so little.

The answer is not raising pay. The answer is effective discipline, which means either real punishment, or real exclusion of kids that won't toe the line. Neither of these things is likely, or perhaps even possible coming from the state. That's a reason that education should be completely private.
