At a rally this summer, Donald Trump touched on the topic of school spending. “We spend more per pupil than any other country in the world, and we’re at the bottom of every list,” he told a crowd in Philadelphia. Cut spending in half, Trump insisted, and the result will be “much better education.”

Unsurprisingly, Trump’s claim is wildly at odds with research on the connection between school spending and student achievement. That more spending, particularly on schools attended by the poorest students, leads to improved academic performance and graduate rates is now so well established that even former naysayers have conceded the point. The evidence regarding the damage done by slashing school spending is also considerable. Deep spending cuts result not in a system that looks like Norway, as Trump opined to the faithful, but in stunted academic and life outcomes for kids.

Twelve years ago, Kansas attempted a radical experiment in tax cutting. Under then-Gov. Sam Brownback, lawmakers slashed taxes on the state’s top earners and reduced the tax rate on some business profits to zero. As one think tankput it, “Kansas Tax Cuts Among Deepest State Tax Cuts Ever Enacted.” The cuts did not bring the promised “trickle-down” economic renaissance. As revenues plunged, lawmakers were forced to make deep cuts to spending, particularly for public schools. By 2016, Kansas had tumbled to near the bottom of state spending on public elementary and high schools.
