I'd be curious to know why someone is greedy if they are selling something for Fair Market Value? Supply and demand/simple economics dictates the price, and plenty of people are paying it. Disney is a business not a charity so they get to choose the price they charge. The rest of us are consumers, not slaves, so we get to decide if we pay the price or not. I'd also be curious to know how many people complaining about the demand pricing model actually buy one-day tickets, as opposed to park hoppers or annual passes, though I realize those prices are going up too. Anyway, not trying to start a fight or derail the topic, but my perspective is that most companies are "greedy", if that is defined as trying to maximize profits. Public companies are legally obligated to maximize shareholder value, if I understand things right.
Disneyland is a luxury, and unfortunately not everyone can afford luxuries. No one is required to reduce the price of a luxury to the lowest common-denominator price. I personally think Disneyland is such a great value that they should do away with the lower pricing on So. Cal passes and have the price start at the Deluxe level. Those So Cal price points are absolute bargains. I wish I could get in at that price rather than having to pay $599 for a Deluxe AP, just because I live somewhere else. But, we had so much fun at Disneyland in January that we upgraded our 5-day parkhoppers to Deluxe APs. Bring on the trips! Back to the topic at hand, if I were to answer the question I'd prefer to say Disney is expensive, rather than greedy, but that just shows that I'm a trained capitalist.

I look forward to hearing other opinions and following the discussion!
