This isn’t conspiracy theory, or ideologically driven slander. Look at DeVos’ own words and actions, over her long career advocating against traditional public schools; her funding of an ideologically driven pro-charter lobby; her willingness to spend whatever it takes to ensure her policy preferences become law.

DeVos is unqualified in every respect to serve as head of this critical department, and the U.S. Senate must vote Tuesday to reject her nomination.

West Michigan billionaire DeVos hasn’t worked in public education, public administration, or even in mainstream education reform. She’s demonstrated a refusal to value outcomes over ideology. But she’s contributed millions to the Republican Party and Republican candidates, to the pro-school-choice lobby she essentially founded, and to like-minded candidates whose careers she has financed.

All at the expense of public school students, mostly black, mostly in Detroit — children a world away from the Grand Rapids area where the DeVos family makes its home.

But nor has she spent her considerable wealth and influence advocating for better schools outside of Detroit; report after report shows Michigan schools are falling dangerously behind, that serious investment and course correction are required to stop this slow slide to the bottom.

DeVos has called traditional public schools a “dead end,” a government “monopoly.” Husband Dick DeVos said the couple bemoans the role public schools have played at the heart of American communities — replacing, they believe, the church as the central institution of American life. She has advanced or lobbied for programs that draw taxpayer dollars from those schools, always to those schools’ great detriment, to fund unregulated charter schools or to provide public-money vouchers for private education.

There’s nothing inherently destructive about charter schools. Properly managed charters can be a viable alternative for parents with few options. But that’s not the kind of charter school DeVos has championed — and nor can an education secretary’s educational advocacy be so one-sided. In Michigan, charter schools can be run by for-profit operators. Charter schools can siphon public money for decades, taking taxpayer dollars without making good on the promise of better results.
