What I feel like I've come to realize is that pride is at the center of it all. Pride is what makes people "quiet" about it , because people don't like admit that they aren't happy. People don't want to spend $500 on a phone, be locked for 2+year, and then admit its a POS (yes, some people do, but far from the majority). People don't want to admit that they hate their job to their closest friends and coworkers unless it's clear everyone else feels the same way.
People lie to themselves (although, they certainly know they are doing it), so that they don't have to admit that they aren't perfect...it's ego...and it's silly (it's the same thing that makes people buy a 2nd car, or a bigger house, because their friends got a 2nd car or their brother bought a new house..)
