From historical perspective, another side effect of "elite overproduction" is that as "elites" grow in number, they take an increasingly larger slice of the pie, eventually leading to peasants rebellions when enough people cannot even feed their families.

And disgruntled elites alone is not enough to start rebellions if they lack popular support.
