Salaries for librarians

I received an e-mail newsletter/update from the University of Illinois School of Information Sciences.  Lots of news about minority recruitment.  I wonder about that.  Librarianship (the old name) requires a master's degree.  With school teachers earning anywhere from $56-$60 an hour, much more than librarians, why recruit minorities?  It's possible that median salaries are listed under some other titles.  Another website listed slightly higher salaries--about $35,000, but nothing that would pay off college debt.

So I sent the school a note:

"I was reviewing “iSchool at Illinois” and what has obviously been a very successful recruitment of minority and male students. I found the microaggression workshop a bit off-putting, but then that's my age--graduate MLS in 1966. From what I've seen of them they are anti-white, anti-male and divisive. So I checked a website for salaries and see a library researcher is $27,848 annually, same as a linen room attendant and $2,000 less than a parking lot attendant/valet. There was no listing for "librarian." Do you have any current salary figures that would make recruitment of men and minorities a worthwhile effort?"
