The National Education Association and the American Federation of Teachers are, along with environmentalists, the most powerful forces in today’s Democratic Party. They elect Democrats, who provide them more jobs and money, which they spend to elect more Democrats, and so on. To keep this political machine going, they need to maintain their monopoly control over public education.
Mrs. DeVos isn’t a product of that monopoly system. Instead she looked at this system’s results—its student failures and lives doomed to underachievement—and has tried to change it by offering all parents the choice of charter schools and vouchers. Above all, she has exposed that unions and Democrats don’t really believe in their high-minded rhetoric about equal opportunity. They believe in lifetime tenure and getting paid.

All things being equal, even if the results are the same, broader choice is better. The intangible outcome of being able to choose is being able to govern your own life.
