those who think that benefit recipients are a bunch of scroungers living off the backs of the workers

Many of these 'scroungers' live in private rented accommodation, so the money for the rent is taken from the 'workers', then, via the 'scroungers', put straight into the pockets of the private landlord. Oddly enough, no-one ever complains that these landlords are living at taxpayers expense and are getting money for, in many cases, doing nothing.
