Yet somehow the other 60%, who are not earning a living wage, are still living. A better name than "living wage" needs to be used if they want me to understand what they're talking about.
Do you require that every vocabulary definition be obvious and intuitive to you before you make an effort to understand the effect being described? Fields other than your own have jargon with its own history and justification, it seems a shallow basis to dismiss data on.
Anyway no one "wants you" to understand anything and won't shape the world so that it's comfortable for you to. If you choose not to try that's on you.
