I wonder what kind of rationalization Bob Dylan, The Beatles, et al went through once they reached 30 years of age. Do they move the goal posts to not trusting anyone over 40? Or do they admit that they were youthful and wrong and state that untrustworthy people, at any age, are the only people that shouldn't be trusted.

Probably both.

The concept in the 60's at least was partly due to change in culture between the young "hippies" vs. the older "man". People were realizing in a big way that "the man" was lying to us... Vietnam War, etc.

Things haven't changed much in that regard, but the corporate/govt media "alliance" has become more sophisticated in dispersing/distracting such anger.

They probably didn't hold the narrow beliefs you are pretending they did so 30 came pretty easy.
