If you want to look at in terms of a purely power based perspective though, not getting mad when someone does something like that is the most definitive expression of one still being in control.

Here is part of the speech and I find it extremely relevant to your article.

“…But something strikes you when you move to America and when you travel around the world: every education system on earth has the same heirarchy of subjects. Every one, doesn’t matter where you go, you’d think it would be otherwise but it isn’t. At the top are mathematics and languages, then the humanities, and the bottom are the arts. Everywhere on earth.

And in pretty much every system too, there’s a hierarchy within the arts. Art and music are nomally given a higher status in schools than drama and dance. There isn’t an education system on the planet that teaches dance every day to children the way we teach them mathematics. Why? Why not? I think this is rather important. I think maths is very important but so is dance. Children dance all the time if they’re allowed to, we all do. We all have bodies, don’t we? Did I miss a meeting?

Truthfully what happens is, as children grow up we start to educate them progressively from the waist up. And then we focus on their heads. And slightly to one side.”
