> You do understand right, that the faculty system relies on a pyramid of people entering and leaving the system? And only a certain fraction getting to the top, and people having to vacate the top of the pyramid for anyone else to get there? (for stable, or in other words, stagnant fields) To put it differently and in terms that's easier to follow and understand, demand for tenured faculty positions is far smaller than the current supply of skilled labour.
