This is really what it all boils down to. If I had a business and could essentially keep charging my customers more and more, with only positive effects to my bottom line, I would become one greedy SOB! People seem happy to just throw their money at them. “Ooh. Orange Bird cups! I’ll take 10 please!”
In their defense, they have finally added real value recently with the new lands and attractions, but they seem in a big hurry to recoup that investment and then some! As others have said, only an economic downturn would likely return things to a more “affordable “ level. Of course, never underestimate the willingness of fans to keep spending money they don’t have.
