That seems completely coherent to me. Getting a job as a teen is good for you. It teaches delayed gratification, working with others, responsibility and it provides a measure of independence early.

Social media, on the other hand, will make teens depressed. The association of social media => teen depression is ~5x stronger than cigarettes => lung cancer, which is a completely unfair comparison for cigarettes because you get the lung cancer 50 years later and you get the depression today.
