"While supply-side dogma claims that massive tax cuts will spur growth and cause wealth at the top to “trickle down,” this has never panned out in reality. Economic inequality has returned to pre-Great Depression heights in America since the Reagan Revolution. One of Reagan’s most prominent economic advisors, Arthur Laffer — who more recently advised Kansas Gov. Sam Brownback — has predictably cheered Trump’s intention to emulate Reagan’s supply-side experiment, predicting that his tax cuts will lead to economic “nirvana.” But Laffer was similarly bullish on Kansas when he advised Brownback to sign radical tax cuts five years ago, and economic nirvana has yet to arrive in the Sunflower State. Duane Goossen, the former budget director of Kansas, observed last October that the Brownback experiment “broke the state budget and imperiled education, highways, and key services without delivering the promised economic jolt,” and has unflatteringly called Trump’s economic plan “Brownback Economics for America.” Trump has proven time and again to have a shallow and limited understanding of the economy — but his economic council of billionaires and Wall Street executives doubtless know what they’re doing. Ultimately, supply-side economics is a dogma that was developed by corporate America and the business class to further their own class interests (see the “Powell Memo”), and viewed through that prism it has been a tremendous success. While supply-side policies have been disastrous for the majority of Americans (and for the overall health of the economy), the wealthiest Americans have seen their wealth surge, which explains why the dogma stubbornly persists."
