I hope we can all agree on one thing, a person's real value has absolutely nothing to do with their family income. Being rich or poor is irrelevant to how good a person is. In fact lower income people contribute a higher percentage of the income to charity than the rich. Further, I agree that using terms like middleclass, upper class and lower class can be considered an insult so I apologize and will only use percentages and quintiles.
Now, it is clear that both Disney and Universal don't go after the middle income family, they go after the top 20%. Even Six Flags and Cedar Fair go after the top 40% of family based on income. The reality is that only people who refuse to admit they are financially well off claim that any of these parks care about the majority of the public. In fact 40% of the families can't even afford a $400 repair bill, so complaining about the cost of tickets to Disney or Universal is ........ One last thing, using ticket prices alone is also irrelevant as family size has decreased substantially since the 1950's. A better number would be to determine how much the average family spent as a percentage of their family income in the 1960's for trips to DL and compare that to today. Of course spending per person is higher today but they are spend on less people today. Walt Disney didn't design Disneyland for the average American, he designed it for his friends and Hollywood.
