I think all of the reasons listed by the article carry some weight. When I was a teenager in the 90s my parents did not want me to get a job, and instead focus on studying. When I finally landed that awesome job making chicken at $4.75 (training wage) my colleagues were older, in their thirties and up, white and African American. Returning to that same restaurant in 2015 I found the majority of the employees appeared to be of Hispanic origin. So maybe it's just a combination.
