Yep. I also attribute it to getting older and more conservative. (actually conservative, not this revanchist destructionism cloaking itself in the label "conservative").

It is an irritating realisation that the ones I though were naive, weren't, but I was for thinking they were naive.

Your usage of the word "naive" to describe how you thought of the establishment is weird to me. I was surely naive. And I still don't even really see that as a bad thing (is it not the job of youth to imagine a better world and push us forward?). But I saw the establishment as more suffocating, tired, preaching to the lowest common denominator, puppets of entrenched interests, etc.
