Trickle Down economics was a Trojan Horse
In the 1980’s Ronald Reagan ushered in a new era in American economics as he cut the top tax bracket from 70% down to 50% and then down again to 28%. In order to get support for doing this from the people, and also from politicians, a very crafty set of lies were produced. As David Stockman, then Reagan’s budget director, put it: giving small tax cuts across the board to all brackets was simply a “Trojan Horse” that was used to get approval for the huge top tax bracket cuts. “Trickle-Down” was a term used by Republicans that meant giving tax cuts to the rich. Stockman explains that:
"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."
"Yes, Stockman conceded, when one stripped away the new rhetoric emphasizing across-the-board cuts, the supply-side theory was really new clothes for the unpopular doctrine of the old Republican orthodoxy."
