age of consent in the United States.

Many municipalities (City, County, township etc) set the minimum age requirements for employees in establishments that serve alcohol. States may set the age of consent, but they rarely set the ages for employees, except for the minimum age to work.

In my state the age of consent is 16. You can be married at age 16, drive at age 16 and you can work at age 16. The local cities set the age for employment in a business that sells alcohol (in my city the minimum age is 18 (they may not handle any alcoholic product. They must get another person who is 20), but if the business serves alcohol, they must be 20 to serve alcohol).
The city I grew up in, the minimum age to work was 15. No one under 18 was allowed to work more than 20 hours a week, unless they had completed high school.

That being said, 18 is considered adulthood in our country. This is the age to vote, serve in the military, age required to carry insurance (under the ACA) and so on. Anyone less is considered a child. Occasionally you will see some heinous crime committed by a juvenile and the prosecution indicates they will be tried as an adult. Anyone younger is a child, legally. Now imagine a club owner who employed a very hot 16 year old stripper. He would be putting himself out there for child pornography, and well as a mountain of crap for exploiting a child in a sex industry.

I don't know of any state that would allow a child to dance topless. Perhaps in other countries, but I don't know about that. At my age, I would be reluctant to pay for a dance from a child, no matter how hot, or how cheap.

In the matter of age for porn, if it’s involved in interstate commerce it’d need federal age limit (18)

Important knowledge for 18 yo men - if they fuck a 16 yo in a state where 17 is age of consent it’s technically statutory rape.

Romeo and Juliet laws can protect them though.
