In some places they also do it to get bigger football players.  Make them repeat early grades too, sometimes.  No, I’m not joking.

When we did our short-lived  stint in public school this was advocated by teachers as much as parents.  “Your son is bored and restless in class so we think it would be good for him to go through the same material next year.”

I guess we are a weird society in what we think should be common and what should be particular.  Marriage?  That’s not a public concern at all.  Education Curriculum?  He need a giant factory to toss all the different children into and they will all come out the other side just the way we want them.  If a kid is not adept in being subject to mass production, then he needs to be shoved through that stage of the machine a second time.

Let us finally consider how naive it is altogether to say: “Man ought to be such and such!” Reality shows us an enchanting wealth of types, the abundance of a lavish play and change of forms—and some wretched loafer of a moralist comments: “No! Man ought to be different” … He even knows what man should be like, this wretched bigot and prig: he paints himself on the wall and comments, “Ecce homo!”

Obviously, I’d apply this differently than Nietzsche.  But it does seems to point to the abuse embedded in a public education philosophy.
