Aside from the fact that you basically guessed at the prices of a lot of stuff and generalized a whole lot of other stuff, thank you for at least attempting the math.
In 1985 there were only two parks; there are currently four parks, so you would expect an annual pass to have risen significantly each time a new park was added. There are more rides, shows, entertainment experiences and attractions in the parks now than there were in 1985, so you have to also factor in that Disney itself has grown along with their pricing structure. The product you get now is bigger and more technologically advanced than what was presented in 1985. You may not think that Everest or TSM or Fantasmic! are worth the bump in price, but they're a far cry from something like Thunder Mountain or Sorcery in the Sky.
Your $125 flight in 1985 vs your $180 flight now doesn't quite take into account the fact that in 1985 your plane had more room, served food, loaded your bags for free, charged far less in taxes and was, IMO, a far better experience. Plus ... that $125 was probably rack rate. The $180 you
can get now is likely based on scouring lots of different websites, buying on the discount, carrying on your own luggage and food, cramping yourself into a seat and being on an absolutely packed airplane. So ... not really the same experience. If you were to compare the $125 flight you paid for in '85 with a
comparable flight now, you'd be flying first class!
My point with the whole exercise is that Disney has raised their prices while also adding stuff -- parks, attractions, shows, rides, landscaping, dining, tours, etc. Gas, milk, bread ... they charge twice as much and give you .... what? Same product. Except in the case of the bread, probably a few slices less per loaf. Your flight doesn't appear to have gone up all that much, but you've lost a ton of services to keep that price low. A flight now is not the same as a flight twenty years ago. And it's certainly not giving you more than you used to get.
And all of that is why I still think of WDW as a value. It's not cheap, but I get my money's worth. You may not feel that way. Or you may actually feel as though you
are getting your money's worth, you're just mad that it costs more. But whether you want to call Disney greedy or money grubbing or whatever, it's comparable to other experiences of its kind. For my family, a single non-park-hopping day at WDW is worth considerably more than a single non-park-hopping day at Universal. And yet, as of this morning, they cost exactly the same. YMMV
