"The High Cost of Low Teacher Pay"
http://www.nytimes.com/2011/05/01/opinion/01eggers.html

If nothing else, here's the first paragraph:

"When we don’t get the results we want in our military endeavors, we don’t blame the soldiers. We don’t say, “It’s these lazy soldiers and their bloated benefits plans! That’s why we haven’t done better in Afghanistan!” No, if the results aren’t there, we blame the planners. We blame the generals, the secretary of defense, the Joint Chiefs of Staff. No one contemplates blaming the men and women fighting every day in the trenches for little pay and scant recognition."
