Slightly adapted from this article where the reference is to health care:

Let us for a moment consider the land of the sane. In the land of the sane, education is a business, and a business generally has two categories of workers: line and staff. Line workers generate revenue by directly participating in the company’s line of business. Staff workers consume revenue in their roles supporting the line positions. A smart business seeks to balance the two kinds, maximizing the number of line positions while minimizing the number of staff positions.

Where revenue is driven by governments cost control all but disappears.
