I can understand the teachers saying it’s a gun at my head, but they’ve got the same gun at the parents’ head at the moment. The parent goes up to the teacher and says, well, I’m not satisfied with what you’re doing, and the teacher can say, well tough. You can’t take him away, you can’t move him, you can’t do what you like, so go away and stop bothering me. That can be the attitude of some teachers today, and often is.

By pursuing his own interest he frequently promotes that of the society more effectually than when he really intends to promote it. I have never known much good done by those who affected to trade for the public good.
