Interesting: although Americans earn more, adjusted for inflation, than they did in 1960, the cost of iconic days out like baseball games or Disneyland is less affordable now than it was then.

Everything is more expensive, but in particular the costs around the periphery have increased to absurd levels: parking at the ball game and Disneyland, popcorn at the cinema.

It illustrates how difficult it is to measure inflation properly – and justifies the pinch that so many people are feeling.
