Working a McJob was one thing when I was in my 20's. Working one now is an eye-opener.
No way can a person work a McJob without having their life subsidized in some way. All income would go to food or rent. Wages will not cover both. The 'get a job' theme promoted in 'Seattle is Dying' has no appeal because it won't work. The American food chain is not set up that way.
Hard cases come in the store to rip us off all the time. My fellow employees want to go medieval on their asses. I fully understand their point of view. Too much 'shrinkage' and the store could close to open somewhere else. The self-justification that one is stealing from a corporation and not employees is not as simple as a twisted conscience would have it. People 'doing the right thing' for minimum reward are also not fond of freeloaders. It is a redneck sort of thing, and the sun has been on my neck.
But the hard cases who match your demographic have no conscience needing a twist into self-justification. They walk into the store to steal and for no other reason. Old beat up cars with a get-away driver. They come in, load up shopping carts, bags and backpacks, then they leave.
What we can officially do is limited. We may not sting. But we swarm.
But that is another story. Humans are creative. The right incentives and tactics of persuasion would reach a majority of the lost if our society provided such things.
Which we don't.
