Why did president hoover's response to the great depression fail open study?

The correct answer is that it was based on protectionism.  

President’s Hoover response to the Great Depression failed because it was based on protectionism.

Hoover allowed the government to intervene in the economy raising the tariffs of the imports. The tariffs were so high on foreign products. Those countries affected by the Roosevelt decision did the same as a counter-measure, affecting the economy of the United States. The excessive government intervention made Roosevelt’s response to the Great Depression fail.
