The gist of it is that there are only three types of people who work in organizations:
1. At the top of the food chain are the sociopaths. Executives.
2. Below it are the clueless, the mid-manager who works nights and weekends out of a sense of loyalty to the company. Unlike the sociopaths and the losers (explained below), they don't have it within themselves to straight up leave the company for something better. To them, this is life.
3. And below that, are the losers. That's everyone else. The pawns in this little corporate game designed by the sociopaths and coordinated by the clueless. They won't be promoted. But unlike the clueless, they have a sense of freedom. They can go work for a competitor if it pays more. Or they'll have a real work-life balance, etc..
It (should be) no more than a humorous take on corporate culture. Don't try to take away any life lessons from this.

Even before reading this I had this vague idea about my own 'checked out' existence that he describes as loser.
I agree though, to not take life lessons specially when people take these things very literally. Because they can really come up with statement "I have worked with some of the smartest 'clued in' managers. So on the face of it 'Gervais principle is bullshit."
I think the Sociopath one is most accurate to life but that's just because "executives/investors are profit-seeking goal-maximisers" is both a common trope and pretty realistic - that's their incentive structure after all.
