Supply-side economics
Supply-side economics or trickle-down economics is a theory that if taxes were cut on the richest people in society, rich people would use their extra money to invest in the economy, but if taxes were increased, the wealthy would leave the country and invest somewhere else where the tax rates are lower.  People who support supply-side economics believe that taxes punished productivity and if they were lowered, people would produce more goods and services.  Many supporters of supply-side economics also support things such as limited government spending, low inflation, and regulating the economy less.
