I think what the clash meant by 10 times worse, was that if you work your whole life at one job and waste away doing nothing, it is worse then spending a small amount of time in prison. I think the whole point of the song is that life is short (hence SOMEDAY YOU'LL MEET YOUR ROCKING CHAIR), people aren't meant to work like slaves in pointless jobs that consume your whole life just to fuel capitilism. I think the point they are trying to make is working a job like that, is like being in prison (or 10 times worse haha).
