Wa wa what?

Call me crazy, but I was a little stunned when I had to pay Laurin's school $81 at registration. Granted, she had a $20 volleyball fee, but even before that it would have been over $60. I know I shouldn't complain and I wouldn't if I didn't already know that our school district receives $7500 per student through taxes and grants. So what does the school do with the extra $30,000+ they receive through enrollment fees? They probably need all that money to buy paper plates and sporks because it's too expensive to hire a dishwasher to wash real tableware.
