The charter school "movement" may be imploding, but it doesn't matter at all to the privatizers. If you are of the neoliberal mentality, you don't believe any public institution is legitimate since the "right" to make money by any means, even through outright fraud and theft, is paramount.
The "charter movement" is just means to the end to all taxpayer-funded education. The neolib/libertarian view is schools--indeed ALL public institutions--should be paid for with user fees like tuition in private schools. If you don't use it, why should you pay for it is their idiotic, selfish mantra. If you don't have the money to pay for your kids' education, too damned bad. They don't seem to grasp the concept of the interconnectedness of generations and of various groups as a part of a whole, that as a society we are ALL in this together.
The main traits of neoliberals are a complete lack of empathy for others and the overriding worship of unfettered greed.
