Explain why Roosevelt's New Deal laws were called "alphabet soup."

Progressive politicians saw their wildest dreams come alive. The Great Depression created an environment where the federal government accepted responsibility for curing a wide array of society's ills previously left to individuals, states, and local governments. This amount of regulation and involvement requires a vast upgrading of the government bureaucracy. An armada of government bureaus and regulatory agencies was erected to service the programs of the New Deal. Collectively, observers called them the "ALPHABET AGENCIES."
