As already stated, in Walt's days the more $ you had, the more attraction tickets you could buy.
Is it fair that those who can afford to eat at table service restaurants in the parks are not forced to eat at counter service locations instead? Is it fair that those with more money can get better souvenirs, or can afford to have someone take their picture for them?
This isn't about a class system, this about a business making money by providing services and products. Everyone can use them, if they choose to.
