I do agree that people looking down upon on youth as restless, unproductive and the like is nothing new.
At the same time, I do feel like our modern society contains elements that have made it way worse then it has been in the past. In the past there was no mass entertainment like television or video games or Twitter/Instagram/etc to keep young people perpetually distracted. There wasn't so much wealth that we could afford to have large amounts of people living in their parents basements smoking pot all day without society collapsing. There was no pornography on demand to easily sap the virility of youth. Even if the IQ of the average person has been getting higher, it doesn't matter much. Intelligence is nothing without a strong will to put it to use.
To sum it up: yes young people have always have a tendency to be boorish but the modern era and all that comes with it just makes that tendency even worse.
