Arthur Laffer’s Theory on Tax Cuts Comes to Life Once More
A white cloth napkin, now displayed in the National Museum of American History, helped change the course of modern economics. On it, the economist Arthur Laffer in 1974 sketched a curve meant to illustrate his theory that cutting taxes would spur enough economic growth to generate new tax revenue.
More than 40 years after those scribblings, President Trump is reviving the so-called Laffer curve as he announces the broad outlines of a tax overhaul on Wednesday. What the first President George Bush once called “voodoo economics” is back, as Mr. Trump’s advisers argue that deep cuts in corporate taxes will ultimately pay for themselves with an explosion of new business and job creation.
The exact contours of the plan remained murky and Mr. Trump will not produce a fully realized proposal on Wednesday. But what the president has called a tax reform plan is looking more like a tax cut plan, showering taxpayers with rate reductions without offsetting the full cost by closing loopholes or raising taxes elsewhere. In the short run, such a plan would add many billions of dollars to the national deficit. Mr. Trump contends that it will be worth it in the long run.
“The tax plan will pay for itself with economic growth,” Steven Mnuchin, the Treasury secretary and main architect of the plan, told reporters this week.
Good - make the cuts deep enough and the economy will boom. Cut regulation, cut taxes and stand back.
