Positivity culture exists because there’s no real downside for the people exuding it. You swing for the fences and the losses and layoffs are someone else’s problem. Most decent people might find such decision making distasteful and that excludes them from leadership.
It's sort of like optimistic concurrency. Sure, transactions straight-up get killed on a regular basis. But if you make transactions cheap things that are easily replaceable, then the overall system might still benefit.
I think that all you really need to do to translate the principle to business culture is replace the word "transaction" with "someone's career".
