I agree with your last statment, Pete, which of course is agreeing with AV's assessment.
Don't you think that this statement may be referring to the very animal that is Disney and not a specific direction they have taken? Perhaps the belief that what Disney has become (the Disney culture), the growth they have experienced (the growth they would have experienced no matter who's path they would have taken) is the root of the problem.
I can't say for sure what the lady meant. But I can definitely say that if she meant what you are proposing she may have, I couldn't disagree more.
The culture that she refers to is one that she believes has literally cheated her out of hundreds of millions of dollars. One of greed and dishonesty. That's her perspective.
That is not inherent to any large company. I'm not naive enough to think that there aren't some people like this in most companies, and that many of them never get caught. But when you talk about something like this being prevalent in a company's culture, no, it was not inevitable, and yes, when a CEO is at the helm for nearly 20 years, he carries the most responsibility.
If you talking more about the type of culture referenced in Roy and Stanley's letters, one of micro-management, intimidation, and looking for the quick buck, then I'd say that certainly that is the easiest direction for a culture to go. But again, not inevitable. And again, a 19 year CEO bears the most responsibility for it happening.
That's not to say nobody else would have taken the company down that path, or even that MOST leaders wouldn't have done it. Only that there are leaders who would have chosen the path less taken, and its somebody like that that must be found to lead Disney.
