Corruption pretty much. The director of the school would constantly pocket a lot of the public funds sent to school and then offload the cost of whatever that money was supposed to go to onto students.

One of my favorite examples of this is this tradition where last year students before graduating are supposed to leave something to the school, and our class was asked to buy new tables, with other classes having to do something stupid like that as well.

I still see the school in the news from time to time being involved in some new corruption scandal lol
