Sure but there is definitely more access to info about what is happening in the world so stuff someone might've had simplistic view on 20 years ago now can be researched and looked at by anyone that wants.

I also think the fact many people work in not really all that creatively stimulating jobs to begin with have a lot of effect on that. When you are at school you learn something new every day and are occasionally facing different mental challenges, when you work at retail not really.
