Not a native speaker, so maybe I got that wrong, but this is the definition Google gives: "having or showing an attitude of patronizing superiority.", and this is what I was referring to.
Agree with what you say about the varying degrees of centralization/decentralization throughout history, but don't think that these changes happen out of the blue. Education is usually needed to bring about change and not because people are dumb, but because information doesn't always gets to them easy. So maybe this is what's happening now. You can think of it as a balancing force...
