There’s nothing that makes being a plumber or electrician inherently more skilled than being a fast food worker.

That might be the dumbest thing I've ever heard. Let's take a plumber they need to be proficient in welding, soldering, pipe fitting, building codes, ... It more than just how to use a plunger.

What are fast food workers training on for 40 hours? What skill do fast food workers starting out posses that's equivalent to welding a high pressure pipe that will pass x-ray inspection.

There's no reason to be defensive about unskilled labor, it's not claiming they are mindless idiots, just that they didn't receive formal training to do their job.
