Jesus, I have never seen a group of people bitch more about school supplies in my life.
Kids cost money. School costs money. Yes, there are lazy parents who won't buy supplies and there are poor parents who can't afford it. And guess what....whether you send one box of crayons or 25 boxes of crayons, that is still true.
If you have a question or don't understand why they need a certain item, ASK THE TEACHER. If you want to know how your school district budgets their money, ASK THE SCHOOL BOARD. (Budgets ARE public record.) If you don't like how the school district budgets their money, RUN for school board. If you don't like the fact that your school HAS no money, call your state legislator.
Buy community supplies, DON'T buy community supplies. Fuck, send your kid with a note around their neck telling the teacher to fuck off....
BUT FOR THE LOVE OF ALL THAT IS GOOD AND HOLY, STOP BITCHING ABOUT IT!
