Public entities do not use depreciation to budget for eventual costs as businesses do, but they instead use a budget device called  reserve funds. The Empire State Building does not need to be replaced because part of its cash flow every year is dedicated to its maintenance. 
It was known since the day these schools opened that they would someday need a roof, new flooring, new bathrooms. At one time the money allocated to these reserve funds would accumulate and then be used for the appropriate replacement items. 
Instead those reserve funds have been been used for other purposes and the maintenance has been allowed to lapse to the point where the district taxpayers are called upon to pay for the same buildings twice. 
I believe it's time to let our children know that someone has to pay for the cost of this malfeasance and that because they don't yet vote we've chosen them. They can get back at us when they refuse to pay 50% of their income covering our Social Security.
