Please extend it to the world: most managers are pretty worthless or worse, a damage. Managerial culture is a damage to the entire society.
When it spread we cease to innovate, to really research, we only popularize and improve (a bit) per-existing techs being unable to really evolve them and create anything new. And the more we advance the worse situation became.
We start to have car's that exhibit astonishing absurd issue like top-line Audi's that lock their driver inside due to an unknown fault (banal things like classic internal door little rod, mechanically connected to the lock mechanism are not there anymore in many models or became a different beast), normally always-working machines that start to exhibit random behaviors and no one can really understand why, not counting big projects that nearly ALWAYS fails from fighter jets to ships to space industry project.
Education itself in terms of formal diplomas became meaningless: personally I "discovered" ancient books (lecture notes) that contains more information, more clearly explained and open a world of possible "evolution paths" that far bigger and expensive modern textbook fail completely to provide only at a fraction.
