Normally I think I would agree with you. Though in the battle of money, the Government, who prints the money generally always wins.
Here WDW I think is a bit different. Sure they bring in tons of revenue to the state, taxes, tourism dollars, ect., Hell they in a big sense made Orlando what it is. But unlike most businesses, what's Disney's leverage against Florida? They aren't like a manufacturing company who could take a sweetheart tax deal and move their plant, or offices from one state to another. I guess they could move their administrative people back to CA, or to some better/cheaper state, but the main buisness, the one that is bringing in all the revenue and tax dollars is a fixed asset that I can't see any way leveraging against Florida.
Can you see any feasible way that WDW could move any operations out of Orlando? They aren't just packing up Space Mountain and moving it and the parks to GA or one of the Carolina's. Hell it's been talked to death why opening up a 5th gate doesn't make alot of finacial sense, multiple that times 100x for any attempt at moving the WDW operations from Florida.
I guess you could argue that WDW could hold back on future investment in Florida, take that 17B and put it....where? Open up a new stand alone destination in NC or Texas? Besides the insane start up and infrastructure costs of building an entirely new domestic destination, you will likely just end up cannibalizing domestic travel demand (in a time when investment rates are up and domestic discretionary spending are anything but certain.) Further investment in CA? Maybe, but is that a good return on investment for Disney, is there space there to expand efficiently? Disney still wants to make money, and right now the cash cow of the whole operation is parks. Is there any action Disney can take that would threaten to have an impact on the revenue they bring to Florida...without impacting the revenue they are bringing to themselves?
