Explanation:  

In the 1930s, the United States went through a period when large numbers of Americans lived in absolute poverty, desperately in need of more food, clothing, and shelter. Paradoxically, the productive resources (farms, factories, machines, labor) that could provide these foods, clothes and shelters were paralyzed: they produced nothing.

In this context, Americans needed Congress to act quickly to contain this crisis, but Congress was slow and inadequate, so Roosevelt acted to strengthen the authority of the office to make policy, arguing that this would turn things around more effectively.
