In the summer of 2018, President Trump sang praises about the country’s economic conditions, tweeting, “In many ways this is the greatest economy in the HISTORY of America.” But just how much of the upswing can be attributed to White House policies?

Summers tells Gillian Tett, US managing editor of the Financial Times, what he would do differently, and the tactics that should be taken to ensure economic growth.
