Well that is quite a bit of spin. Two glaring contextual flaws I see in your argument. For one, I live in the midwest. Anecdotally, I don't know a single person around me who makes $80,000. The Median income is highly skewed by areas of the country flush with money like NYC, LA, San Fran, Miami, Austin, etc.
"In simple terms, if Warren Buffet walks into a room in which there are 80 guys who are dead broke, the moment he’s there, they’re all billionaires, on average. Because Buffett is worth over $81 billion, and 81 guys divided by any number over 81 billion means that on average, they’re all worth over $1 billion."
"The top 5% of US households earn as much as the bottom 60% combined. The top earners skew the mean, or simple average income number, much higher than the amount the median, or exact middle-of-the-pack household earns"
"And what we find is that for all the purported progress and recovery and great stock market and all the rest, the real household median income, below which half of all US households fall, is around $45,000 and about half the mean income of almost $90,000"
Secondly, you conveniently choose to use ticket prices as your only metric. Everyone here knows Disney is not in the business of making profits at the turnstyle, it's the $4 water, the $20 hamburger, the $75 t-shirt, the parking, the resort fees, and soon the $15 per person fast pass. They make it on food and merch not unlike a Movie theatre. Speaking of which I bet you could create the same metric for theatre ticket prices over the years, but you will have failed to mention how expensive the popcorn and soda are. Theatres make next to nothing on the actual ticket prices same as disney.
You have cherry picked a very specific metric to suit your argument.
