Its not about that.

It's way easier to control people in an office.

Employees have to submit to groupthink and can be monitored and caught alot easier if they dont submit to this groupthink.

It's a lot easier to control people through groupthink than via reason.

In an office not only do you have to do your job but you also have to be "a person the group would want to have a beer with".

You don't want to lose your job for not being a cultural fit do you?

So management has a lot more control over the situation.

Ive been depressed and withdrawn and just focusing on work before and been called into managements office and told Im not "acting like myself, is everything ok?" with a bit of an ominous tone and so I had to pretend to be outgoing and cheerful when I wasnt.
