Question

President Reagan's supply side economic policies called for tax cuts/benefits for the upper class that were supposed to eventually "___" and help lower income Americans

Answer 1

trickle-down--the idea behind supply side economics is the money would transfer to the lower classes through jobs and wage increases. 

Supply side economics provides tax cuts for the wealthy to encourage investment into new jobs or provide wage increases for workers. This policy only works though if employers move the money down.
