Explanation:

Conservatives generally believed that the economy could rebound by itself, and that the government only needs to react within boundary or not react at all. This can be seen under the leadership of Herbert Hoover, who left it mostly to the people to solve the problem. With the leadership of Franklin D. Roosevelt, the government stepped up and tried to solve the problem. Of course, like most government plans, it may not have been the best, but, as the quote goes: "If it works, it works". The economy was soon able to rebound, and became alive again following the US entering World War II, with a booming economy towards the end of the war.
