The fulcrum occurred in 1984.2 things...have you ever waited at the Apple store for customer service? I don't think it's that great...all they do is say your phone needs to be replaced after waiting for an hour. Secondly, you stated "Once Walt left, the bean counters took over" First off, Walt didn't leave, he passed away...BIG difference. If you stick by your logic, since Walt passed away BEFORE WDW even opened, I guess the world has been inferior since day one.
Up until then, WDW was run by those who personally knew Walt Disney and closely followed Walt's vision. Some even complained it was an anchor weighing down every decision.
Michael Eisner and Frank Wells took over in 1984. They were outsiders with no ties to Walt Disney.
After a rough start and some serious pushing by the Bass family (Disney's largest shareholders at the time), Eisner and Wells began to invest heavily in WDW starting in the late 1980s.
Investments continued until 9/11, when everything in the travel industry changed. That's the second key date in understanding the investment history of WDW.
My original post explains this. You might want to take a few moments and read it, if you have not already done so.
