Conor P. Williams wrote an article for the 74 Million on the potential effects of what Secretary DeVos won't do as opposed to what she will do:
Much of the public concern about Education Secretary Betsy DeVos has consisted of folks burning themselves up speculating at the damage she’ll actively do to public schools.
But much of this sort of hand-wringing about DeVos is misplaced. Given the limits that Congress placed on the Department of Education at the tail end of the Obama administration, her ability to make states hew to her agenda is limited. What’s more, the public’s general disinterest in education as a political issue will also limit DeVos’s room to maneuver. Specifically, while Americans often express concern about the state of public education, they’re generally comfortable with their own schools. This means that any dramatic changes to American schooling usually come with greater risks than rewards.
