We had a great music director once, now world renowned (we never deserved him), who believed in blind as in blindfolded auditions.
Whoever the candidates were, whatever their backgrounds and accolades and educations, he didn't care. No one was to know who they were rating, and after a while there were complaints of bias... for talent.
During that period, yes, there were more women and people of color chosen than historically comprised their body, but they were from everywhere. It turns out musicians didn't want to be reduced to bigoted demographics, so it attracted many more "non-traditional" candidates when word spread you could make it on merit.
Blind auditions were scrapped when he left, and so did actual diversity. You can include everyone today in a single introduction by mentioning Yale, Juilliard, Paris Conservatory, Royal Academy, etc.
Merit destroys class privilege, which is a big faux pas when your patrons tend to be family of people who want to advance their careers in your institution. Just recently, I couldn't help but notice the timing of the creation of another superfluous position being filled by a fledgling choral director and a $MM donation by his parents to expand the performance hall he'll be using.
Mere dutiful patronage, surely, in these times of austerity.
