There is absolutely a correlation between education being focused on female success (a combination of predominantly female teaching staff and optimising for traits generally held by women such as agreeableness) and the trends we've been seeing for 30 years now.
Unfortunately this is not the popular narrative, but it does need to be discussed.
EDIT: I, unlike the parent, am not trolling, so if you're going to downvote I would prefer a rebuttal.
Citation 1 (agreeableness as a direct consequence of academic success): https://www.sciencedirect.com/science/article/pii/S104160802...
Citation 2 (women on average are more agreeable than men): https://doi.org/10.3389/fpsyg.2011.00178
Citation 3 (Gender distribution of academic success over the last few decades): https://w3.unece.org/PXWeb2015/pxweb/en/STAT/STAT__30-GE__04...
Citation 4 (Gender distribution of teachers in the USA): https://nces.ed.gov/programs/coe/indicator/clr
Citation 5 (Gender of teacher affecting academic performance of same gender): https://www.journals.uchicago.edu/doi/10.1086/696203
So we have direct correlation with a personality trait, it being attributed to a sex and a seeming consequence.
I could be wrong, but while correlation does not equal causation: this does seem to be a very strong correlation.
