"Trickle-down": supply-side economics creates tax cuts for the wealthy.
Supply-side economics suggests tax cuts for the wealthy. Those tax cuts will be used to create new jobs. New jobs will give more money to the middle-class.
This economic policy makes sense in theory and in some cases the tax cuts resulted in more jobs and higher wages. However, mostly it led to a large gap in wealth as the wealthy kept the money instead of reinvesting in jobs and wages. Eventually as the US moved industry overseas, tax cuts for the wealthy meant the expansion of jobs overseas instead of American jobs. Meanwhile the middle-class pay higher taxes to make up for the loss of taxes from the upper class.
