The term "supply-sider" refers to an individual or group of individuals who adhere to the supply-side economic theory, which posits that economic growth can be achieved by increasing the supply of goods and services. Synonyms for "supply-sider" include "proponent of supply-side economics," "supporter of trickle-down economics," and "advocate of Reaganomics." Many supply-siders believe that tax cuts, deregulation, and incentives for businesses can stimulate economic growth and create jobs. Critics of the supply-side theory argue that it primarily benefits the wealthy and does not address issues such as income inequality.
