If by Disney you mean tickets to Disneyland and similar theme parks, then pricing rising above inflation actually reflects wealth inequality getting smaller, not bigger. A lot more people in the world than in decades past now have enough wealth to consider traveling to one of the small number of Disney theme parks in the world and spending time there, and there's only so many people who can fit in the park at once. The Disney corporation could (and has) built more parks around the world, but maybe you care about Disneyland specifically, and there's only one of those today just like in the 1950s when it was built.
