How did the new deal of president Roosevelt exemplify the solution of the economic crisis theory of john Maynard Keynes?

President Roosevelt's New Deal exemplified John Maynard Keynes' economic theory by emphasizing government intervention to stimulate demand during the Great Depression. Through a series of programs and reforms, the New Deal aimed to create jobs, boost consumer spending, and restore public confidence in the economy. By increasing public expenditure and supporting infrastructure projects, the New Deal put Keynes' ideas into practice, demonstrating the belief that active government involvement could help mitigate economic downturns. This approach contrasted with the prevailing laissez-faire policies of the time, highlighting the necessity of fiscal policy to foster recovery.
