Donald Trump’s tariff war is usually framed in terms of how it would impact consumers and America’s relationship with other countries, but it is also part of a larger project to remake taxation policy. Trump is very explicit that he wants tariffs to replace personal and corporate taxes with tariffs as the main source of revenue. As such, tariffs are a sales tax, of a particularly regressive sort. I talk to Marshall Steinbaum, an economist at the University of Utah, about how tariff’s fit in with Trump’s larger social vision of a plutocratic society, something that can also be seen in how the White House is cracking down on student debt holders. We take up this and other economic matters, bringing a class analysis to the business news.
