Econoclasts: how Reagan saved the economy

Sound money and low taxes.

Here’s a review of the new book about the history of supply-side economics. I suggest any candidate, Republican or Democrat, read the book for a simple explanation of what makes the economy stop and go, and an untangling of the failed theories which keep driving us into the ditch.

As Americans contemplate slow economic growth and a spiraling dollar, Brian Domitrovic’s new book, “Econoclasts: The Rebels Who Sparked the Supply-Side Revolution and Restored American Prosperity,” should serve as a roadmap to revitalizing the private sector. This sharply written, thoroughly-researched narrative weaves together financial history, economic doctrine, and character study so skillfully that recent decades’ policy debates become not only comprehensible, but at times, downright exciting…

Supply-siders believed if investors, entrepreneurs, and business owners were incentivized to work, save, and invest at the margin – i.e. to take new risks – expansion would result. In this view, production led to consumption and was therefore paramount.…
