Yes, it is fair. Younger people (Below 18) need to focus more on school. Work can take their attention off of school. And without school they wont be able to get a better job. Plus younger people can only work part time due to child labor. Most workers below 18 also have parents that's job is to feed and care for them, which means they do not even need to work until they are over 18. most people that work under the age of 18 is just for the fact of having money, not because they need it to live.
