Trickle down theory
Trickle down theory is the idea - falsely attributed to conservatives - that helping rich people will indirectly help the poor. People who attribute this idea to their opponents also generally refer to tax rate reductions as "tax cuts for the rich". But the trickle-down effect is (at best) an oversimplification of an idea originally championed by U.S. presidents Wilson and Kennedy, as well as economist John Maynard Keynes. These men suggested that when tax rates are too high, tax revenues suffer; so they suggested that a reduction in tax rates could increase tax revenue (see Laffer curve).
