To go back to the original topic - during the boom years when I knew of several perfectly healthy fit people sitting back and claiming unemployment benefit, I would certainly have agreed they should have been made get up off their lazy a*ses and do something for the community.
But nowadays we have thousands of people who have worked hard, paid their stamps and been let go from their jobs totally against their will. I really don't think it would be fair to add to their misery by forcing them to go out and do menial jobs to 'earn' their benefit. Many of them will, of course, seek voluntary work themselves in order to do something with their time. But they will probably volunteer for something they feel will give them some satisfaction, or an area where their skills might be useful.
