By and large, the desire to obtain an MBA and move into a management-consultancy/thought-leadership type role is directly connected to a preference to avoid doing hard, meaningful work and preferring instead to operate one layer above a grift.
People who choose this path are explicitly saying they wish to operate as your superior, and your work product is theirs to dispense with as their vision decrees.
I doubt there's any new human behaviour at play here, but it does seem to be more encouraged/accepted to be a quasi-parasite than it used to be. On the flip side they're not wrong, hard work doesn't pay.
Hate the game?
