I don’t know which generation you’re from, but I never got the idea that it was blaming any particular generation. At the time the movie came out it was referring to a generation that didn’t exist yet. They were more commenting on the direction we seemed to be going: the priorities of capitalism, our devaluing of education, and our celebration of ignorance. These were all issues that were systemic starting well before I was born. Which is ironic considering Carl Sagan said the same thing a decade prior, pointing to Beavis and Butthead as an example (Mike Judge made both Idiocracy and Beavis and Butthead).
