It's the same situation at the universities.  More and more part-time faculty, short-term contracts, and the only growth and full-time jobs are in the administrative offices.  For all of the people who don't like public service unions, that's understandable, but how do you feel about senior administrators who are beyond incompetent and self-serving and pulling in six-figure salaries?  Most of them are major narcissists who have never worked in the private sector and are only concerned with empire building using public funds.  The last people that these administrators are concerned abut are the students and the quality of education.  To them students are just "funding units" and are referred to as such behind closed doors.
