I don't think it's pyrrhic at all. They get fewer public teachers, get to push homeschooling and expensive private schooling, and push education out of the hands of people that can't afford it. Now you've got even more people who won't learn that America is built on atrocity after atrocity, and will become violent when anyone even hints that it might be, completely oblivious to the irony because nobody taught them what irony is.
Meanwhile, the people responsible for it are completely isolated from any consequences and are instead reaping financial benefits.
