Which of the following is an accurate description of the theory of trickle-down economics?

"Trickle-down economics" and "trickle-down theory," is a term used in politics to classify economic policies perceived to benefit the wealthy and then "trickle-down" to the middle and lower classes. The theory states that if the top income earners invest more into the business infrastructure and equity markets, it will in turn lead to more goods at lower prices, and create more jobs for middle and lower class individuals. This sentiment is captured in John F. Kennedy's argument, "a rising tide floats all boats". Proponents argue economic growth flows down from the top to the bottom, indirectly benefiting those who do not directly benefit from the policy changes. However, others have argued that "trickle-down" policies generally do not work,and that the trickle-down effect might be very slim.

Today "trickle-down economics" is most closely identified with the economic policies known as Reaganomics or supply-side economics.
