Washington, D.C. Schools Chancellor Michelle Rhee is doing it again: handing out pink slips to underperforming public school teachers, 241 last week to be exact.

A note of envy creeps into this New York Post account of Ms. Rhee’s latest action:

Imagine if New York City schools were allowed to dismiss the worst-performing 6 percent of their teachers: How many tens of thousands of students would be saved from years of stunted educational growth?

The article also hails Rhee’s firings as “the result of a weakening of job-for-life tenure protections Rhee won last month in talks with the Washington Teachers Union — though the union now says it’ll contest the firings.”

Here’s the question: Do schools exist to educate young people or to provide tenured jobs for those who aren’t good at educating young people?
