Administration staff has been beefed up during declining enrollment to maximize state and federal funds. The larger school districts have staff dedicated exclusively to researching and applying for grants. At-risk kids, non-english-speaking kids, kids with learning disabilities, low-income, single-parent, minorities, large families, children at risk due to absent or incarcerated parents --- you can find a bucket of money for any of these if you know where to look.
These "administrators" administer funds, not children
I have heard of Schoold Districts which have the administrative staffers pay pegged to the teacher's scale and therefore can't increase teachers wages because the corresponding administrators' wage increase, of their much higher salaries, "breaks the bank".
