Well, there are other things they can do, including extending hours. But that costs money instead of making it, so it seems very unlikely.
The main thing I hate about all these systems is that they create the feeling of "haves" and "have-nots," which I had never experienced before at a Disney park. For a long time I was definitely in the "have not" group, but I felt like Disney was a place that welcomed me anyway. Once I walked through the front gate, we were all equal and just having fun. There's a real psychological cost to watching people stream by you while you stand in line, and it's not a feeling I had ever had at Disney before. It adds a nasty component to the parks that for me damages the brand and my entire perception of the place. Even when I'm the one with the pass, I still find it uncomfortable.
The world is such a divided and angry place now, I want my one place where we all get to be in the same happy boat. Too dramatic for a silly theme park? Probably, but it's one of the things that contributed to making Disney the happiest place on earth, and now it's gone.
