The Clash know the only thing worse than experiencing unemployment is experiencing employment. So they're bitching about the options available to undereducated young men with limited skills and unlimited chips on their shoulders, and they're delighting in seeing the working world for the stultifying nightmare it is. A job is a means of control: it's meant keep you out of trouble, keep you in line, keep you stifled and unimaginative. And unless you're planning to rot in the gutter, you've gotta have one. So just sing along and make the best of it. And yes, they really do want you to sing along. Which is why this is something close to a novelty number--a song with a punning chorus and jokey lists of dead-end jobs in the verses, a song defined by a simple, insistent beat that's easy to sing along to. Who doesn't want to sing about how work sucks? And what could be easier to sing along to than that thump-thump-thumping beat? Sing, wage slave. Sing for your new masters. Sing!
