I think what I meant to write is that ‘one’s gain is not balanced out by an equal loss to another person’. And there are plenty of places where a zero-sum mindset might make sense, e.g. if you work for a small non-growing company the only real opportunity for career advancement may be replacing your boss, but most people who can work in tech can find somewhere to work where they can create value rather than just move it from somewhere else.
