Actually, no. 2007-2016 is very evident of this. Bob Iger joined and said all he was going to do was invest in the current four parks, and they really sucked at that until Avatar opened. The biggest "MK expansion" in history was not even an expansion. Laurels rested in that area when things were always praised and money was good is one of the reasons things are playing catch up now.
And they gave up on maintenance standards for many things, which would make no sense
If people did not "crap on"/not see the value ideas, we may still have those cabanas in Tomorrowland and bad show transportation in the back of each theme park.
