At what point does this kind of behavior warrant a replacement of 100% of the executive staff? How can we make such a mechanism a reality to incentavise and encourage better behavior?

Utilities are too damn important for the bottom line of humanity to allow things to continue playing out in the same sad, pathetic, greedy fashion. The point of having public utilities is to enable a high standard standard of living so hopefully the really important problems can be solved before it's too late. PG&E seems to think the primary goal is for the utility company to be politically powerful and make cush millions for the execs. Sickening.
