Unfortunately, the data supplied by @
Rob562 mixes some apples and oranges, comparing old tickets with a "no expiration" option with new tickets without the "no expiration" option. Price increases for the "no expiration" option have skyrocketed (for example, 7.4% in 2012 for a 10-day ticket) but let's set those aside since most don't purchase them anymore.
When first
introduced in 2005, an adult 7-day base MYW ticket cost $199. In 2012 (still waiting for 2013 price increases) that same ticket costs $288, an increase of about 45% or 5.5% annually.
A 7-day "park hopper" MYW ticket could be purchased for $223 in 2005. In 2012, that ticket costs $345, an increase of 55% or about 6.5% annually.
In general, ticket prices for children have increased even more as Disney closed the percentage gap between adult and child. Thus, for example, 2012 was the first year where adults and children were charged the same price for a WDW AP. An adult AP increase 10.6% in 2012 alone and a child's AP even more.
For comparison, median household income has increased about 10% over the same period. Obviously, wages have not kept up with the price of a WDW vacation meaning, every year, fewer can afford to vacation at "the place where dreams come true".
Not a problem for CEO Bob Iger who received a 20% pay increase last year. Iger's increase alone was enough to employ several hundred additional full-time CMs at WDW.
As recently as the early 1980s, the average CEO-to-worker pay ratio was about 30-to-1. Iger's ratio is about 2000-to-1.
