Amazing that the Republican party is still dominated by such a thoroughly discredited economist. It's time for some new ideas, folks.
"Laffer’s ideas have also grown out of fashion with much of the mainstream economic community. There is an entire branch of economic literature that uses detailed equations to show cutting top tax rates does not spark additional growth. Most recently, the University of Chicago’s Owen Zidar showed that the biggest gains from tax cuts come when rates are reduced for low-income workers.
"In 2012, the University of Chicago’s Booth School of Business asked a panel of respected economists from across the political spectrum whether they believed an income tax cut today would lead to higher tax revenue five years from now, compared with a world with no tax cut. Not a single respondent said it would."http://www.washingtonpost.com/business/economy/arthur-laffer-has-a-neverending-supply-of-supply-side-plans-for-gop/2015/04/09/04c61440-dec1-11e4-a1b8-2ed88bc190d2_story.html
