WDW used to be much, much more affordable. From the day the Magic Kingdom opened until EPCOT Center opened, a park ticket (adjusted for today's inflation) was about $25 a day. When EPCOT opened, the price jumped to about $40 a day (in today's prices). It steadily rose through the 80s and was about $65 all through the 1990s. The big greedy increase occurred from 2000 to 2010 when the price (in today's dollars) went from $70 to $100. Ten years later, we're now at $130. If park tickets today were the same value as they were in 1982 (start of EPCOT), they'd be $40, not $130.
And that's just the park tickets. Factor increases in costs for food, hotels, parking, merchandise, after-hours extra ticket celebrations, reduced hours of operation, etc. They are intentionally pricing the middle-class out of the parks.
EDIT: Another example: In 1982, the annual pass was $100. In today's dollars, that would be $280, not $1,300.
