I don't know. I think it's too convenient to blame this solely on devices and internet and such.

I'm certain that they are a symptom, but I am unconvinced that they are a sole cause for this

Edit: Obviously not a psychologist, but just from what I observe: People have had way higher expectations from life than ever before in the past, and life has not really been meeting those expectations.

A lot of people I know simply aren't going to enjoy the same luxury that they grew up expecting, being told they would have, that they were "promised".

We are inundated with more choices and decisions than ever before, causing stress that becomes overwhelming.

Up until the last generation, you didn’t even worry about what you were going to have for dinner. Your option was whatever was available. You spent the day making that thing. You ate. Now you have to make decisions on every little thing in life because there are options and choices for everything in life. We have not yet evolved quickly enough to handle this many choices and decisions, as lame and unimportant as they may seem.
