Well... I've managed various people so far and while yes, most are simply way to uneducated/illiterate to work properly in the present world in their roles, they are still capable to learn if properly driven. I've observing that treating people like humans instead of meat-based bots do makes them much more human and a step at a time a team change.

Of course you can't transform things in a snap, but a change is possible if properly conducted. The issue is more the unwillingness of those who conduct than the reactionary ignorance of most.
