I feel like it doesn't help that more people are traveling to Orlando. I did some fact checking - 1990 claimed 14 million tourists, while 2017 reports 72 million. That's hecka amounts of tourists. I think we can all agree it's gotten more crowded at the parks, and sadly, ticket prices increases are one of many ways to try to remedy that.
EDIT: Some USF relevant numbers: 2.8 million visited in 1990, 10.2 million visited in 2017. (Courtesy of theparkdb)
