Dig into trickle-down economics, which claims that tax cuts for corporations and the wealthy stimulate the economy and improve people's lives.--In 1981, the US economy was struggling: unemployment rates were climbing and inflation had peaked at an all-time high. To combat these issues, President Reagan introduced a number of economic policies, including tax cuts for large corporations and high-income earners. But did these policies actually stimulate economic growth or improve circumstances for Americans?
