I'm talking for people I've known who were in this situation because they won't talk about it themselves... Because they are introverted they are only going to talk about it with people they are close to. I've been close with a lot of introverted people because I love getting to know people and I care about them.
You seem to think that introverted people are not as good as everyone else because they struggle to make friends. That is fucked up. That is the kind of shit they deal with all the time and you wonder why so many introverts have social anxiety.
I never said all work relationships are shallow and I'm not devaluing shallow relationships either. I'm saying shallow relationships have less value for introverted people and it takes social energy for them to participate in these relationships that could be better spent elsewhere.
I personally love being in an office where I can spend time with my co workers. I go to the social events, I spend time with them outside of work. Because I have more social energy than introverted people and I don't care that I won't see most of these people in a few years.
I personally think the ideal situation for an introvert is a long term job working at a small company with the same people. Unfortunately that's hard to come by. Most introverted people would be better off with remote work because they can then live in the same city as their close friends and don't have to expend so much social energy just to get a paycheck.
