For linguistics? I can't speak for the others, but I know that linguistics departments are pumping out a lot more PhDs than there are positions in the field. I expect that is true for all of them. Because these fields don't tend to bring in grant money, I expect professors can't demand rock star salaries.

But if your ratio of professors to students is poor, your department is going to be a money drain even if its demand in salaries and facilities is low.
