I saw that President Trump is awarding the Presidential Medal of Freedom today to economist Arthur Laffer. Laffer was a top advisor to President Reagan and a proponent of supply-side economics. He established what is known as the Laffer Curve, which showed that increases in tax rates eventually cause government revenue to decrease. So with the Laffer Curve cutting taxes stimulates the economy and actually ends up increasing tax revenues.
24/7 News Source reports that last year, Laffer co-wrote a book called Trumponomics: Inside the America First Plan To Revive Our Economy.
