Earlier quoted context omitted.
What skills does a line cook at Wendy’s learn aside from “how a job works?” Also, who staffs Wendy’s from morning until schools let out during the day? I haven’t seen seasonal fast food restaurants anywhere near me.
General multitasking, team coordination, cash handling, basic restaurant dishwashing, stock management, industrial cleaning, pacifying unhappy customers, dealing with druggies and harassers, and a whole bunch of other things I've probably forgotten from when I worked fast food as a teenager. The simplicity of each individual job means that nobody ever has just one job at a fast food place. Stick around for any amount…
That's why the pay is low, because the skill set is widely accessible. I'm not sure why people insist that these kind of jobs are teaching valuable skills.
All that is happening is the basic process of working. They could learn it in any context, at any point in their lives. There is no justification to pay people starvation wages.
