I don't really want the thread to derail into that area, it always ends badly. But your analogy is very, very flawed. Yes, you are wrong.
I can choose (and I most usually do) to not go to football games, not buy NFL t-shirts, not go to certain concerts, or not buy certain CDs etc. I cannot choose not to pay my property tax.
The teachers union is powerful enough that 'free market' simply does not apply. Why do higher demand math and science teachers get the same pay as teachers in high supply subjects? That says it all - that is not the free market at work. Do all NFL or entertainers get the same starting pay?
And for the record, I never 'complain' about teacher salaries directly. I only complain that there is not a free market for teacher salaries.
