Also there have been demonstrated to be other ways around the problem of educated population. Divide them against other classes of the population for example. Or subsidize and encourage non-productive people.
And even if everyone was educated and wanted better, how would they ever vote for more individual rights and freedoms if the suppression of those rights is the only thing keeping them safe from other groups in their country?
All authoritarian societies have their priesthoods, knighthoods, police forces, scribes, etc., or their modern equivalents, essentially a small middle class afforded more wealth and more rights than the peasantry.
Couple this with the fact that educated people often buy into authoritarian ideologies. At least that’s what I’ve seen. If there is any legitimate basis behind American anti-intellectualism this is it.
I'm also hopeful that the requirement for a well educated workforce will nudge societies towards more freedom than the historical norm.
