Child labor was a commonplace, if contentious, practice for much of the first half of the 20th century. During the progressive era, various state level laws were passed to regulate and limit the practice. New York’s celebrated Factory Investigating Commission, created in the wake of the Triangle Shirtwaist Fire, addressed child labor as much as it did fire codes. The Keating-Owen Act of 1916 attempted to ban the interstate sale of any good manufactured by American children, but the Supreme Court overturned the law. It took the Fair Labor Standards Act of 1938, one of the last New Deal laws, to finally put an end to most child labor in the United States. The law covers most people under the age of 18.
