Why would you say that capital is able to use critical thinking and self-exploration to increase exploitation and control? Why self-exploration, first of all.
As far as critical thinking goes, I can see the truth of this statement, but only in a pretty trivial way, in that the ability to reflect and think critically is a source of power no matter what your purposes are. Any ruling class having to deal with changing circumstances is going to need this. And any disaffected or unruly class is going to need this if they want to shake off the exploiters. Why then is giving kids that ability going to, in the balance, work in the interests of capital?
How is it that keeping people alert, in-tune, and savvy works as a method of control?
I keep asking because I've reread the thread so far and you've just been restating variations of this thesis. I haven't yet seen your argument for it.
