Inexpensive Overcrowding Remedy

Mayor Bloomberg loves to take decrepit, overcrowded high
school buildings and magically turn them into small schools. Here's his recipe:

Take one school building created for 1800 kids,
currently housing 4200. Add five layers of administration.
Give each a worthy sounding name, like NY Academy of Art, for
example. Devote several classrooms to the additional administration, and dump the displaced kids in some trailers out back.

Then, add a few hundred more kids and voila! You have a decrepit,overcrowded high school building containing five impressively named academies!
