Turning a good technician into a mediocre boss destroys value
In companies (public or private), one way to progress economically is to acquire responsibility for the work of others: to move from being a technician to being a boss.
However, the skills that define a good technician are different from those of a good boss.
This causes many good technicians (motivated by economic incentives) to become mediocre bosses: they do not have the skills needed to be good bosses.
For the company, this situation destroys human capital value: we have turned a good technician into a mediocre boss.
