I think that Edison would have been having fits for years.
I agree that GE has struggled for years; personally, I think the issues predate neutron Jack, though he really didn't help things. I think that GE make an excellent case for teaching how not to manage a company, though GM comes close. They stopped listening to their customers and engineers, and middle management papered over the issues to be promoted to senior management. Not every plant or division was / is poorly run, but many were and there was no systemic effort to move best practices throughout the company, which is a loss for everyone. Contrast this with, say, McDonald's that requires suppliers to share best practices with their competitors.
I think that it is incredibly hard to change corporate culture, especially when times aren't good.
I have my grandmother's wedding present GE toaster and love it. It still makes excellent toast. I don't think that I own or have owned another GE product that I can recall.
Love the logo.
