This is OP again. Thanks for bringing this up on the listserv, but the discussion there rivals DCUM and it's not anonymous! I think part of the problem is that there is a perception that either you "can't afford" $40 and you're FARMs or you can afford it. What about federal workers who are afraid the govt will shut down? Have gone without a payraise for 3 years? Or those who were laid off and accumulated credit card debt? Why should a "free" public school charge $40 for this?
And frankly if it's divisive, why not do away with it? When I was a kid, my friends gave me their phone numbers and I called up!
Are you talking about people who live in the [very expensive] Bethesda ES school district and are federal workers and they can't come up with $40 once per year? That sounds like mismanagement of finances or freeloading to me.
