If you are a historian, you have to have a long memory or know where to find out what you need to know.

I remember when charters first started. One of the arguments that charter advocates made was that they would cost less; they would be more efficient and would save the taxpayers’ money. After all, they wouldn’t have all those administrators and overhead found in public schools.

But as time goes by, charters are forgetting the original promise (they never made them) and demanding parity with public schools.

That’s the purpose of the “Gates Compact,” where the Gates Foundation gives a district a big cash award if they agree to treat charters on equal footing with public schools.

And now we see charters in Pennsylvania making a plea to up their state reimbursement for tuition.

In a time of fiscal austerity, every dollar that goes to charters comes out of the budget for public education, meaning less money for public schools.

Charters are learning that the cost of education is what it is, unless you pay teachers less or make a point of having large numbers of young, inexperienced teachers who are at the bottom of the salary scale. Or, go online, in which case, students can be put in front of a computer and the virtual class size may be 50 or more, with none of those pesky brick-and-mortar expenses, like heating, cooling, custodians, a school nurse, a library, etc.
