"When first proposed by now-discredited economist Milton Friedman, “Trickle Down Economics” was sold with the promise that if the wealthy were to gain more wealth, through tax incentives and corporate welfare, that glut of wealth would spread throughout the economy through investments, sales, etc. After 40 years, we have to conclude that there is no trickle down."
