In that case, you probably would want a letter every month acknowledging the school's hard times and deficits with maybe you showing how you can relieve the strain on the school -(which nevermind, needs to fundraise to close the gap in tuition for all of us.)
It is mind boggling watching the kochos, mesiras nefesh and stress which goes into running the finances of a school on a daily basis!
A) Not sure about your childs school, but we do get a letter a few times a year for fundraising. Raffle by Chanuka, dinner in the winter, gifts for the rebbiem/teachers for yom tovim, etc.
B) Schools should be more transparent with their financing.
C) No one is saying that it doesnt takes mesiras nefesh and stress to run a school. But you know what also takes stress and mesiras nefesh? Running fiances for your family. Especially during a global pandemic when people are suffering financially. Just like we should acknowledge our schools mesiras nefesh (which the school gently reminds us a few times a year) here in an unprecedented situation, where the schools are probably getting funding, it would be nice from them to acknowledge us as well.
