I live and work in countries with good social security nets and less overtly dystopian work conditions (not perfect of course). I still agree with his advice. Work is a game we play for money. No more real than a choreographed dance. Companies do not really care for you, that should not need stating. Your coworkers might, and if the ones you're friendly with are high up or influential, things might seem like a family. It's actually an in-group.

Don't waste your time trying to be collectivist in an inherently individualistic system. You need to play the game by its rules if you want any results. And less stress.
