Calling them "prevailing wages" doesn't make them any less subpar.
They are not subpar for the industry.
So what is “prevaling” wage for a pizza industry worker and what is”sub-par”?
Sub what par?
We’re taking a job which most anyone can do with a few minute’s training. Show up for the designated hours, flatten some dough, sprinkle assorted customer-chosen toppings thereon, put it in an oven, move it to a box when it pops out, run cash register as appropriate. This is not hard; tedious and tiring, perhaps, but not beyond most people. All the equipment & consumables are provided to the employee at no cost thereto and are designed for ultimate ease of use. There is nigh unto no risk to the employee (in health or finance), hiring is trivial (so long as the help is needed), replacement is easy. The cost to automate the work is little different from paying humans to do it, so raising pay suggests replacing workers outright is a sensible option.
Now, given that job description, what makes what they’re paid “subpar”?
