The response that best captures how "trickle-down economics" differed from economic strategies used in previous administrations is:
"It involved cutting taxes for those at the top of the economic ladder."
Trickle-down economics, which became prominent during the Reagan administration, emphasized tax cuts for corporations and the wealthy with the belief that these benefits would eventually "trickle down" to the rest of the population. This was a shift from earlier economic strategies that often focused on more direct support for the middle and lower classes, as well as increased government spending to stimulate the economy.
