I haven't read this book yet but it sounds like an interesting title on the concept of securing living (and family) wages in society, ideally voluntarily but I think the author might argue for the government to intervene to do so (and was referenced in an article on the topic, I think as one of perhaps the first books talking about this from this theological perspective).

This is obviously a problem as an individual worker needs to be able to earn a living to survive, and likewise the breadwinner(s) of a family need to be able to earn a living "family wage" in order for their family to survive.
I was curious where people think that wage injustice exists today and what might be done to remedy the problem.
