It was an easy to predict consequences of the shift of paradigm in the last thirty to forty years.

With the removal of companies middle layers, paths from operational positions to top management have basically disappeared. That means that at most companies, top managers have made their whole career there often starting in corporate finance jobs or at management consulting firms and have no experience whatsoever of what working for them as an employee is like.

Usually the army fares better here because it still promote from inside its own ranks but apparently it was not enough to avoid this.
