Eli,
What type of Asifa do you want there to be about tuition? Do you want to tell parents they should pay, I am sure you will still gripe about paying. Do you want to talk about the high price? That depends on the community. The people who send to the highest priced schools are the ones the least likely to go to an asifa to listen to rabbonim. Vdal.
All of your issues are for the most part individual issues, not affecting everyone and as such are more appropriate for individual attention rather than a communal gathering.
You sound like the ” counter demonstrators” to the Asifa, they would not listen to anything any Rov says regardless of the message, venue or presenter. Are you of the same hypocritical mindset?
