Keynes was concerned with government influence in times of a recession.
John Keynes was a British economist who focused on trying to understand the Great Depression during the 1930's. While studying these causes, he developed a concept known today as Keynesian economics.
In this theory, Keynes argues that there is bound to be prosperous and awful times in a free market society. Depending on what the economy is doing, government should adjust accordingly. For example, during a time of great economic success and prosperity, the government should scale back their influence/spending in society. However, when the economy is struggling, the government should increase spending and lower taxes in order to help the American citizens.
