This is an interesting world view. Although I seriously do disagree with the "individualistic" part, the rest is on point.
But the coldness is not the cause in my opinion. I think that the true problem with this society is not described with the word "cold" but "deaf".
I see many people in this word going through their rutine not seing or hearing desperate pleas for help from the closest ones around them. Even people in "debates" usually just listen for weak point in the arguments to exploit instead of focusing on the pain behind the arguments.
The cold feeling of society seems like an inevitable consequence, since no matter how much you scream, they will not hear you. People were never tought how to listen. And the few truly open people in this society are usualy that way only after they were forced by a huge pain to slow down.
