Retarding the cost of tuition, I certainly agree.
I do not understand the breakdown of religious schooling costs.
I sure wish that someone in the know could post a fairly detailed summary of how it works. While I am sure that there are costs that are hidden from the customers, a little knowledge would go a long way in helping us understand why tuitions are so high.
Some questions that come to mind:
Yearly property taxes
Cost of insurance
Cost of infrastructure (upkeep and repair)
costs of running the place (electricity, heating, AC, water)
before taxes salaries: Principal, teachers of various levels, support staff
teacher/pupil ratio
Then throw in:
cost of full tuition
number of pupils paying full tuition
average tuition subsidy
number of people receiving average subsidy
Stick all of those into an excel sheet, and things should more or less match up.
