I don't think you understand the market Eoghann.
Customer's "pushing back" is done by not buying the tickets. So, as EricInPA said, if they sell out at $150, then they under charged. It's very simple.
The only stockholm syndrome I see around here are the people who think it is their right to be able to go every year (or even multiple times per year), and be able to afford every single add-on. I'm surprised people aren't complaining about their $1,000+ VIP tours they offer, which is essentially a guide taking you from ride to ride on a schedule that hits all the major attractions.
Many people see Disney as a once in a lifetime vacation. They save up, they binge, etc... If a person decides it is worth it to them to spend $150 to stay until 2am, eat ice cream all night, and ride some rides, then why do you give a crap? Because by paying for it your afraid your going to get priced out? If that's the case, then this is more about you then them. THAT is how capitalism works.
