I don't have a problem paying for my child's school supplies and you are right we do need to take care of OUR kids, but when parents don't why is it okay to expect all the other parents to supply all the classroom supplies, yet its not Okay to expect the teacher to?
I know how much teachers pay for with their own money. I personally haven't met any teachers who weren't willing to provide needed supplies for their class, I just don't understand the attitude that we shouldn't expect them to have to contribute yet its acceptable for the teacher to ask parents to send in supplies to pool them
Now, since this has to do with specific requests, in regards to everyone's shrinking budgets, maybe teachers shouldn't be asking for Crayola over Roseart, or fabric book covers over free paper bags, pr bags of candy, or $12 a box American made pencils

I understand the want for better quality, but sometimes people can't afford all those top quality supplies, sometimes parents can't drive all over creation finding them. I don't think its too much to expect teachers to take that into account when making up their lists.
