At Walmart most of the time you can just fuck around and not do much work, if you get fired at Walmart you just go fuck around at an oil change shop until they fire you. I know men that have done this their whole lives.
To me, a large part of the actual problem here is a marketing problem. It's really hard for a small shop to market that "hey, we need workers, we are willing to pay a premium, and no we aren't a scam company".
Working in "the trades" is an entirely different thing.
There are hundreds of Dave's at corporate Walmart, and they care so little about the employees at any given location that they probably wouldn't even return an email, let alone talk to shift workers face-to-face.
What I do isn't really relevant unless you're trying to make some personal slight.
I believe fairly competent cabinet assemblers / installers are making $40-75 / hour depending on location. Everyone else paying less is half-assing it or doing a poor job.
That's not the point anyway, working entry-level retail is pretty much a 0 stakes job — quality has been mostly engineered out of it. Even a basic cabinet assembly job requires some quality control. Some people do not want to do anything of quality.
IMO we'd all be better off if people had a universal basic income and these people could spend more time finding something else to do with their time.
