That's why they have one of highest crime rates in the world, stopping benefits doesn't drive them to find a job it drives them to crime, the same would happen here, also if they made people work for their benefits, they would simply turn to crime instead then the do-gooders would say "it's not their fault, they can't afford to eat so they steal", get tougher on crime with real prison sentences and hard labour, then a set time period on benefits could work because crime wouldn't seem so attractive.
