If you run an anti-harassment office and you get rid of harassment, you are out of a job and out of power. If you keep finding more and more harassment, you are set for life. Plus if you try to tone it down there's 50 juniors behind you with dubious degrees that will gladly denounce you for being too old fashioned and take your juicy position for themselves.

I don't think getting more middle-managers will ever get this issues any better because it's in their interests to increase their power as much as possible, not solve anything.
