The organisation which calculates the living wage was mentioned in the article. The term "decent life" is obviously subjective, no one has the same values and therefore what someone considered valuable won't be considered as being valuable by someone else. This is what Conservatives mean when they focus on individuals. However there is a way to calculate what people can be able to live on comfortably.

who gets to determine what is "acceptable" ?
If a worker becomes a parent and has twins, should the employer immediately increase salary because the strain of 2 extra mouths requires additional income?
What if an employee determines that they NEED to live in a better neighborhood, should the employer increase their salary?
