It seems to me that they're only "hard to persuade" because they are constantly bombarded with these mental viruses. There was (books/telegraph then?) radio, then TV, then internet, social media, scrolling social video... While it's true that each generation eventually develops some immunity to their entertainment afflictions, it does seem to be accelerating, and those not exposed as youth have less immunity (grandpa on facebook). It also seems to have continuing impact even if most become functioning members of society.
