When women and gays get access to the institution, it's no longer prestigious.The Left's high-minded task of breaking the "glass ceiling" that suppresses, in particular, women and gays is as perenially doomed as that of Sisyphus. When the institution finally gets breached (i.e, the Left has kicked in the door, torn out the windows and knocked down the walls), high-performing males just decamp to the next unclimbed mountain and start again.
There are numerous examples, trivial and non-trivial:
The American Kennel Club competitions are mostly women and gays parading around their genetic-freakshow accessories. Men get tired of these poor schizophrenic, dysplastic beasts (and their dogs) and concentrate on schutzhund performance. (Form follows function, an elusive concept to the feminine brain).
The US military is becoming a gay, female pageant. So men just use it to punch their ticket on the way to jobs in the federal intelligence and defense bureaucracies. Or to the merc companies and getting paid $125K a year to be an international bad-ass.
The mainline Protestants: old queens and their female friends play dress-up and call themselves "priests" and "bishops." Men start playing golf on Sunday. Or join the ancient Apostolic rites.
I need a sociologist to describe and explain the phenomenon in scientific terms. Also, The Last Psychiatrist has talked about this before.
