On a grander scale, this happened in the Soviet system -- people gradually stopped believing anything they were told by "authorities." That phenomenon was even stronger in the satellite countries.
It seems to me "believe nothing from authorities" has been taking hold in the US as well -- fostered by the Tea Party as well as by conspiracy theorists and whistleblowers and social media. When we can no longer believe in our systems of information, systemic revolution (and/or collapse) may not be far off.
I mostly think that it's about time.
