I am not disagreeing with you, just wanted to point out that the age minimum in the US is set at the federal level, and then the states can further restrict; I don’t think they can go below the federal limit:
The Fair Labor Standards Act (FLSA) sets wage, hours worked, and safety requirements for minors (individuals under age 18) working in jobs covered by the statute. The rules vary depending upon the particular age of the minor and the particular job involved. As a general rule, the FLSA sets 14 years old as the minimum age for employment, and limits the number of hours worked by minors under the age of 16.
Absolutely agree.
Btw, the entertainment industry has also gotten their way with child labor, I just noticed this for CA: https://www.dir.ca.gov/dlse/MinorsSummaryCharts.pdf
Sometimes we forget that child actors are labor too.
