So are you saying that the new successors to GE have no agency at all, and they are just following a script? That's ridiculous. The CEOs of GE have not been great or successful but that's on them, not Welch.
Presumably Welch believed in the hiring system he put in place. It was also an audacious claim, which comes with its own rewards. But folks like you let Welch have his cake and eat it too: he gets the praise for making an audacious claim, and then when it turns out false, folks like you make excuses for him.
It's good to be the king, I guess.
