Reagan always preferred big tax cuts for the weathy over balancing the budget.
President Reagan's Director of the Office of Management and Budget, David Stockman, said, "Kemp-Roth [Reagan's 1981 tax cut] was always a Trojan horse to bring down the top rate.... It's kind of hard to sell 'trickle down.' So the supply-side formula was the only way to get a tax policy that was really 'trickle down.' Supply-side is 'trickle-down' theory."
