What of the following ideas is a major element of trickle down economics?

A major element of trickle-down economics is the belief that benefits provided to the wealthy and businesses will eventually "trickle down" to the broader population through job creation, investment, and economic growth. Proponents argue that tax cuts and incentives for the affluent stimulate spending and investment, leading to increased productivity and higher wages for workers. Critics, however, contend that this approach often exacerbates income inequality and does not always lead to widespread economic benefits.
