You can make numbers say anything you want, it's a great way to pull people into an arguement. But that 8-10% is quite generious. Even the Magic Kingdom one day pass, which has seen larger increases than most, has only averaged an increase of 4.7% per year over the last 10 years. Also, I am not sure where you get the 2.5%, but there is all sorts of ways you can look at wage increases. For instance, the most recent data I saw showed from December 2018 to December 2019 the US saw an average wage increase of 5.2% Regardless of what data you look at, these numbers will assume all classes, but as much as we wish it were possible, not all americans can afford WDW, and those portions of the US unable to afford a trip traditionally have a much slower average growth of wage. What does that mean, the average person that goes to WDW (or any vacation for that matter) will have a much higher average wage increase then what the national average is. So based on those "numbers" one could argue the average WDW guest is having a larger wage increase than the average ticket price increase.
Again, you can make numbers say anything. I just had to point that out because your numbers were certainly being generious to try to make your point.
