December 1918
The simple answer is that children were being mistreated, thus a law was passed to prevent this.
In 1916, Congress passed the first child labor law called the Keating-Owen Act. Two years later it was struck down by the Supreme Court in 'Hammer v. Dagenhart' (1918). In 1924, Congress tried again, but the measure was blocked. In 1938, President Roosevelt signed the Fair Standards Labor Act, which included among other things, limits on child labor.
Child labor is already illegal, and employers who employ unreasonably young children can be punished. No new Child Labor laws have been passed because it's unnecessary to pass them.
Many states had passed laws regulating child labor, minimum wages, and working conditions.
The 1864 Labor Law was passed to encourage immigrants to come to America to become laborers,since war efforts(civil war) had reduced the labor supply.

During the Progressive Era, which spanned from the 1890s to the 1920s, one significant act that was not passed was the Child Labor Law of 1916. Although there were efforts to regulate child labor, including the Keating-Owen Child Labor Act, the law was ultimately declared unconstitutional by the Supreme Court in 1918. Additionally, while various reforms occurred, comprehensive federal regulations addressing issues like women’s suffrage and civil rights for African Americans were not fully realized until later.
It was signed into law in 2002.
