Nope. People are more literate today than 70 years ago. People are better educated today and have more schooling. On average, more people have read a full book than before.
Strange to think that people are nostalgic for an era were women ( half the population ) were discouraged from going to college and minorities were denied equal access to education. Even stranger that people think that people were better educated then.
It's statistically impossible for your version of the past to be true.
