The topic of child labor evokes strong emotions and old stereotypes, such as the chimney sweeps of Dickensian London. The good news is that nowadays child labor can be more pleasant and more rewarding. The bad news is that the question of how to protect working children is more complicated. A lot of children are grossly underpaid — not necessarily by the master sweep, but by their parents.

More and more children, by which I mean minors below legal working age, are producing content as online influencers. A lot of Instagram or YouTube or TikTok accounts feature such children, and they can be cute, endearing or (depending on your mood) annoying — as well as profitable. By one estimate, the most successful children working in this area — called “kidfluencers” — can generate more than $20 million a year in revenue.

Their work may be a far cry from the labor of the chimney sweeps, but work it is, at least as the concept is understood in America circa 2023. These children are under pressure, whether from their parents or from their algorithms, to produce content on a regular basis. Being a child social media star also involves a potential loss of privacy and a reframing of one’s image with one’s peers, which may be either positive or negative. And these children can be quite young. One star of a YouTube channel with more than 35 million subscribers, which started out as a toy-review site, was 7 years old in the channel’s early days.

Legally, these children have no claim to the income their sites generate. Thankfully, many parents are loving and generous. But not all. There is no data on how social media earnings are distributed within the family, but the long history of child movie and TV stars indicates that many receive little or nothing.

Enter the state of Illinois, where a recently passed law gives successful child social media stars a right to some percentage of the earnings they generate, to be held in a trust in their name until they turn 18. Such legislation has precedent. In the early days of Hollywood, California passed the Coogan Law, which gives child actors a right to a certain percentage of earnings, which employers have to place in trust accounts. New York has passed similar legislation.

The social media case is tougher to enforce, because often the parents themselves are the de facto employer and there is no contract specifying terms. And how is the relative contribution of the child to the family income to be assessed? (Time spent on-screen? Cuteness? What if the social media presence leads to a book contract or podcast?) Nonetheless, the law sends a clear signal that the children do have some rights to the generated income, and grown children can sue their parents if the money is not passed along.

Labor markets work best when there is a clearly defined notion of consent. But that is hard to come by when children perform services for their parents. What if a child expresses a desire to quit performing on social media, and the parents respond that such income is needed to send the kid to college, or pay for the family home? On what basis could the child’s response be considered as fair, well-informed, and not under duress? It is neither practical nor desirable for the state to insert itself into family decision-making on a regular basis.

Given these problems, it’s probably wise to pare back expectations of what “kidfluencer” legislation can accomplish. At the same time, it is probably better to do something rather than nothing, if only for symbolic reasons and because this sector of the economy is likely to grow.

At the margin, more protection for children’s rights also may boost child labor supply, and in a beneficial way. When I was 12 years old, I started winning money in chess tournaments, and my parents let me keep all of it. A year later, I was giving chess lessons and being paid for it. Not only was I earning money from my labor, but I like to think I helped other players get better, and maybe earn some money themselves.

In retrospect, I am glad I acquired those skills and experiences. But not all cases of “child labor,” if I may use that phrase, are so positive. And for every kid (and family) who tries to earn early income, many more will fail and be left with nothing.

It’s possible, of course, that granting kids greater legal rights to income might encourage more children to seek to become social media stars. On balance, I am OK with that outcome. But it is by no means an easy call.
