A lot of that article seems to be implicitly based on the premise that those who "don't work more" simply do so because they're less inclined to work (or because it would apparently land them in a worse position than working as much as they do) - I wonder where exactly does the Dire Straits interpretation fit into this: "I used to like to go to work, but they shut it down / I've got a right to go to work, but there's no work here to be found"...?
