"There may be disagreements on the numerical effects, but the principle has worked in the past (JFK and Reagan) and will work in the future.
A 20 percent corporate tax rate, immediate full expensing, repatriation of U.S. corporate cash overseas, and a 23 percent discount for sub-chapter S pass-throughs (much credit to Senator Ron Johnson for this) will generate way more growth and investment than mainstream forecasters suggest.
