Actually its been shown that in a slow economy, giving money to idle workers has a stimulating effect on the economy since those workers will spend pretty much all the money they get. With a stronger economy there is more job creation leading to less unemployment and reducing the need for money to be given to idle workers.
Regarding your 'point' of a job, economic value is twofold - first is the worker's contribution to the end product (whatever that may be); second is the worker's participation in the economy by spending the money they make in their job. These two things are inextricably linked to have a functioning economy - without production by workers, there is nothing to buy; without spending by workers, nothing gets sold. So an increase in standard of living can come about two ways - lower prices via higher productivity, or more purchasing power by workers via increase in salary or other means.
