Believe me, you could fire half the adminsitrators in some districts and never know the difference -- and move into smaller buildilngs. These districts spend money on adminiistrator salaries and office buildings like crazy. Teachers are always last on their list in terms of who might get a raise.
Think steel buildings... The local school district here in Katy, TX spends approx $90 million on JR & SR High School buildings...which includes mosaics, murals, marble, imported tiles, etc...
Did I mention that they also build 3-story parking garages for all the kids that drive to school?
Administration has been fattening up to be sure, but when the National Education Association wants the salaries of teachers to go up 19 percent in one year (an actual proposal in a school district near me) that's too much. Especially considering the average salary is over 48-thousand a year in that school district. That would mean a three million dollar expense in a school district with a 37 million dollar budget. (An eight percent budget increase just for teacher pay.)
