Earlier quoted context omitted.
Many corporate boards have an "executive chairman" which means the CEO is also the Chairman of the Board. Perhaps even more importantly a substantial number of board members are executives from other companies, meaning CEOs sit on each others boards and wash each others' backs.
I have to wonder if it should be considered a legal conflict of interest for a CEO to sit on the board at all, forget being chairman. The powerful really love rigging stuff in their favor huh
You say that like there's anybody that doesn't. The powerful just have more scope to actually do so.
