By your definition, yes, I went to an ordinary school.

My personal experience is against your position, for what it's worth.

>>> Their paymasters want high-value cogs.

> If what I wrote was drivel, it should be very easy to refute.

You made the claim. You have the burden of proof. Show that either the educational bureaucrats have a "paymaster" that is different from the state bureaucracy, or that the higher-ups in the state bureaucracy want "high-value cogs".

Let's say there is a city (somewhere in the northern half of the US) that has seen better days, due to the rise and fall of local industry in the 20th century, and there is a town/suburb that has much higher property values and better schools. The students in the suburban school(s) are much more likely to go to college than in the city schools. The suburb is nearly all white, with lots of parents with well-paying STEM jobs, while the city is not. De facto segregation. Which public school is "ordinary"?
