The modern era of national regulation began in which decade?

• A. 1920s
• B. 1930s
• C. 1950s
• D. 1980s

Answer: (B)

The essential idea here is when the federal government first built a broad, coordinated regulatory state across the economy. The modern era of national regulation begins in the 1930s, when the New Deal era put the federal government at the center of economic and social oversight after the Great Depression. This decade saw landmark laws and agencies that established sweeping regulation—financial markets were reined in with acts that created the Securities and Exchange Commission, social welfare and labor protections were expanded with the Social Security Act and the National Labor Relations Act, and regulatory bodies were created to enforce these rules. This combination of comprehensive statutes and new institutions marked a shift from earlier, more limited or sector-specific regulation to a nationwide framework that defined regulatory policy for decades. The 1920s didn’t inaugurate this modern reach, while the 1950s and 1980s brought further reforms, they didn’t start the era.
