I am not disgusted with their behavior really. People take, it's on our nature. If you give an inch they take a mile. I can tell you though the husband is profoundly unmotivated despite having a growing family. He has been able to cruise along thus far not really bothering to give a shit because it's not yet mattered. And that has to be in part because of benefits given to him. They pad the slack. He is a recent vet so has a bunch of money for college but is just dragging his ass getting it done, and so instead makes last I heard $11/hour working some menial office work. His sibling harps on him to buck up but, meh, whatever can't be bothered, it's working okay so far so what the hell.
The fact remains that the system provides those $11/hr jobs by the million. If your guy moves up, somebody else will just get his old job. And it's not like everybody gets to do so, either- any organizational chart tells us that.
It's not about one guy going somewhere, but about a system that provides places to go & decent livings for people who don't go much of anywhere. As more is automated & offshored, as inequality gets greater, there are relatively fewer places, let alone desirable places, to go wrt employment.
We need to figure out how to better deal with that, how to better reconcile protestant work ethic with the amount of work there really is, and how to keep people going in the face of a scarcity of employment & depressed wages.
I don't really know how to do that, but I'm sure that traditional conservative values & philosophy about work never anticipated this.
