“Government really sucks.” This belief, expressed by the just-confirmed education secretary, Betsy DeVos, in a 2015 speech to educators, may be the only qualification she needed for President Trump.

Ms. DeVos is the perfect cabinet member for a president determined to appoint officials eager to destroy the agencies they run and weigh the fate of policies and programs based on ideological considerations.

She has never run, taught in, attended or sent a child to an American public school, and her confirmation hearings laid bare her ignorance of education policy and scorn for public education itself. She has donated millions to, and helped direct, groups that want to replace traditional public schools with charter schools and convert taxpayer dollars into vouchers to help parents send children to private and religious schools.

While her nomination gave exposure to an honest and passionate debate about charter schools as an alternative to traditional public schools, her hard-line opposition to any real accountability for these publicly funded, privately run schools undermined their founding principle as well as her support. Even champions of charters, like the philanthropist Eli Broad and the Massachusetts Charter Public School Association, opposed her nomination.
