Yeah, this is the result of decades of work by right-wing groups to destroy public education and sell the "cure" in charter/private schools. The countries with the best education systems, unsurprisingly, have extremely rigorous standards set by the government and in many cases the methods and materials are produced by the governments, as well. The US's public/private brainworms destroys everything it touches. Which, critical support and all for destroying America, but millions of kids are absolutely fucked by no fault of their own because capitalists wanted a dumb, complacent army of labor.
