For example, most PM books offer very general advice and frameworks, not specific or concrete knowledge - repeating the same superficial information, without much practical insights.

My hypothesis is that a lot of people got where they are from plain luck, but later justify their successes as "hard work" and create a story to sell themselves as "changing the world".

Does anyone feel that a lot of jobs are bs, paid by the rich to stroke their egos, keep their privilege, and prolong these self-perpetuating lies? Or that most "professionals" are subconsciously or intentionally lying their way through and feel proud about it?
