Book excerpt: Conservative economists offer a well-informed defense of Trump’s approach to trade, taxes, employment, infrastructure, and other economic policies. Donald Trump promised the American people a transformative change in economic policy after eight years of stagnation under Obama. But he didn’t adopt a conventional left or right economic agenda. His is a new economic populism that combines some conventional Republican ideas—tax cuts, deregulation, more power to the states—with more traditional Democratic issues such as trade protectionism and infrastructure spending. It also mixes in important populist issues such as immigration reform, pressuring the Europeans to pay for more of their own defense, and keeping America first. Coauthors Stephen Moore and Arthur B. Laffer worked as senior economic advisors to Donald Trump in 2016. They traveled with him, frequently met with his political and economic teams, worked on his speeches, and represented him as surrogates. They are currently members of the Trump Advisory Council and still meet with him regularly. In Trumponomics, they offer an insider’s view on how Trump operates in public and behind closed doors, his priorities and passions, and his greatest attributes and liabilities.
