Trickle down economics was invented by conservatives in the 1980s to justify massive tax cuts for the wealthy and corporations. It’s been nothing short of a disaster.
@rbreich I would argue Reagan’s first tax cut — top rate from 70% down to 50% — was needed. The low inequality of the late 70s caused problems with the investment side of the economy (aka supply side). Every tax cut since then, however, has just made the rich/powerful excessively rich/powerful.
