My conjecture is that this is a widespread condition:
There was a combination of reasons why I decided to leave teaching, but the one foremost in my mind was this — I came to the conclusion that about a fourth of the students in my classes were in the wrong place. They were wasting their time, my time, and theirs’ or their parents’ money.
The issue, as I saw it, was their lack of intellectual curiosity. There’s nothing inherently wrong with that. We all have different interests. Some were there as a way of delaying adulthood for four more years. (Many of them managed to do that for five, six, or seven years.) There’s nothing essentially wrong with that either, but it ought not be subsidized with taxpayers’ money.
