I've never heard of registration fees. I think it'd totally be a great idea to say "let's add $20 to each registration fee and tell the kids to bring nothing but a backpack." What do they say the registration fee is for??
I taught in Texas for 5 years before becoming a SAHM. Supply lists are annoying to me as well. I want all science folders to be green, all math folders blue, etc. So when kids show up with all orange folders, it drives me bezerk. And it needs to have brads for what I'll use it for in my classroom and of course they got the folders with no brads. Maybe that's why they're so specific with the list?? It'd be easier on the teachers, in my opinion, if I was given $400 to buy the supplies I WANT for my classroom. Then I could keep a classroom set of scissors and we wouldn't have to re-buy more the next year, same for rulers, crayons, etc.
Either the district personnel makes the list or a group of that grade's level teachers sit together and agree upon a list. It's never going to be a list that your child's teacher specifically made (unfortunately).
As for a ream of paper -- I always LOVED getting a ream. At the most recent school I was at, we were allocated a certain number of reams each month. Having a ream or two stashed in my classroom was always a nice treat. But it's expensive. And you are completely right - your TAXES are paying for the school building, the teachers' salary, etc and SHOULD be paying for the paper and ink used to help teach your child.
I could go on and on. Definitely don't blame the teachers. If anyone cared what we wanted, we would change it to fit our needs (and therefor the needs of our students). Sounds like district personnel and superintendent trying to milk the parents for all that they can at the beginning of the school year, when you're shelling out money for supplies, registration, school clothes. Next you'll get a letter to join the PTA for a fee. Fun eh?
ADDED:
Teachers are always wanting more Kleenex boxes. Luckily one teacher seems to get a lot more than others. My last year teaching I gave away probably 6 boxes to other classrooms. We also love dry erase markers. Is that on the list? The teachers horde them like they're gold.
