Definition of Common good is doing what the political establishment sees as good for preserving their power.

It's not what's good for you, it's what's good for them.

This is some weird revisionism. The definition of a common good is what's good for a community.

Your definition is weird idealism from the past that doesn't work in today's corrupt political landscape.

Just because politicians are misusing a word to justify corruption doesn't mean the word doesn't have an actual meaning.

There's this weird effect I've noticed where people act like words don't have meanings any more. I don't know what to call it.
