Papa,
Do you or your wife attend your PTA/PTO meetings? At ours, the fundraising and budget stuff all gets discussed (raising funds for maintenance on the Playground, fundraisers, PTO spending, etc...). It can be pretty eye-opening.
At our small school, the PTO has had a few good fundraising years and has purchased all school supplies for the kids the last few years. Once in a great while, the teacher might ask for something to be sent in (tissues, paper cups for drinking out of the sink, craft supplies). I'm always happy to send in something.
Because our PTO pays for the school supplies, they keep (at the school) the reusable school supplies (scissors, rulers, pencil boxes) that are still in good repair and we only buy a few of the reusable items and then all new consumables (crayons, folders, pens, erasers). Our PTO's spending this fall for school supplies was less than $10 per child.
Also, the PTO gives each teacher a stipend of $600 to spend on school supplies that might otherwise come out of their pockets. There's also a small fund for Room Mom's to spend on holiday parties.
At our school, the PTO pays for all cultural & enrichment activities, all field trips, and the playground equipment (erection of the original playscape, maintenance of it, balls & jumpropes for the kids).
I, too, would prefer not to be nickel and dimed with little fundraisers. Send me a letter once a year asking for $X to cover my child's portion of the budget and I'd be a happy woman. Some of our fundraisers are a LOT of work and raise relatively little money, when compared with the number of hours people put into them.
If you have any concerns about how the money is being raised or spent, you might be able to get more information by attending a PTO meeting and/or talking to your daughters' teachers.
