How does supply-side economics differ from Keynesian economics?

Supply-side economics focuses on boosting economic growth by increasing the supply of goods and services, primarily through tax cuts and deregulation to incentivize production and investment. In contrast, Keynesian economics emphasizes the importance of aggregate demand in driving economic growth, advocating for government intervention and spending to stimulate demand during economic downturns. While supply-side theory prioritizes producers and supply chains, Keynesian economics prioritizes consumers and overall demand in the economy.
