” the minimum wage law”
One of many intrusive laws coming out of the Depression. There was a whole raft of laws passed enabling bureaucratic regulators to control business.
Only to be matched by Lyndon Johnson’s even more pervasive intrusions into daily life courtesy of civil rights legislation. God forbid that average Americans not be controlled by someone.
Have you read Burt Folsom’s “New Deal or Raw Deal?” Terrific non-economist expose of creepy Franklin’s power grab.
