It's a good point. I'm speaking of high school who are allowed to legally work in the state of Iowa. If a 16 year old willfully employing themself in an entry level job is considered exploitative child labor to you, I don't know what to say. One sad effect of the changes in labor in the state is that only citizens are beholden to labor laws, whereas those working under the table are not. So it's true there is child labor. The families and farm companies break the law because they still make more than they would back home, but it's less pay than what they are owed under the law, and the parents will lie about their child's age so they can begin working a few years earlier than they are allowed. It causes a cycle of poverty because the kids get used to the farm and they miss out on proper schooling.
