It's not just about money. There are a number of factors coming together to create this monster. The 2018 book "The Coddling of the American Mind: How Good Intentions and Bad Ideas Are Setting Up a Generation for Failure" by Greg Lukianoff and Jonathan Haidt is a great read, which expands on their article in the Atlantic in 2015. The book doesn't focus on gender identity exclusively but does address the way that gender ideology and pronouns have been treated in education, which the authors argue has origins in three "great untruths": (1) "What doesn't kill you makes you weaker"; (2) "always trust your feelings"; and (3) "life is a battle between good people and evil people" Gender ideology as an issue should not be analyzed entirely separately and without regard for companion issues like critical race theory, which are part of the same cultural zeitgeist.
