I have figured one thing out! The news. The news was better 40+ years ago. Because we all watched pretty much the same news programs, they were far more accountable. They couldn't just lie on TV and get away with it. And the fourth estate in general had a higher standard.
You know what they didn't have in airlines 40+ years ago? In-flight entertainment systems. No movies. No TV. No music. No games. Just use your phone? Nope. They didn't have those either. IF it was a long flight, a single monitor might show a single movie. And you had to crane your neck to see it.
