Read it and be afraid. Be very afraid. The barbarians are already inside the gates.

I recollect one time when as a graduate assistant at Marquette, I had an office with two other TAs on the second floor of what was then the Math building and is now not there at all. Three other TAs had the office next to us. The rest of the math department was on the third floor, where they needn't associate with us peasants. The remainder of the 2nd floor was given over to something called the Education Department.
One day, we math grads fell into discussion with one of the Education professors regarding the New Math, in which little kids were being taught abstract set theory. At one point we objected that not even the teachers understood such abstractions. "The teacher does not need to understand the material," the professor of education insisted. "He only needs to understand how to teach the material."
All hail Common Core, where a kid can be marked wrong for showing that 5x3=15 because 5+5+5=15 rather than 3+3+3+3+3=15 as the syllabus says!
