Final answer:
The use of the commerce clause during the 1930s gave the federal government(s) increased power.
Step-by-step explanation:
The use of the commerce clause during the 1930s gave the federal government(s) increased power. The commerce clause, found in Article I, Section 8 of the U.S. Constitution, grants Congress the power to regulate commerce among the states. The Supreme Court's interpretation of the commerce clause has varied over time, but during the 1930s, the court began to interpret it more broadly, expanding the federal government's authority over various aspects of the economy.
