The sad fact is that the people best suited to thrive in a context where relationships are transactional and mostly dependent on continued usefulness to both parties - are sociopaths/machiavellian types.

And these are precisely the people who are most okay with shouting from the rooftop that their company is the best in the world - then doing so from a different company 2-3 years later.

It's good for mental health to understand that. These people do not have better jobs or work for better companies on average - they just say they do because it's better for their career and have no shame or accountability in doing so publicly.
