What you need, peter, are some immigrants who are not entitled to benefits. That's the way we do it in Ireland!
I used to be of the same opinion as you, peter, now, not so much. What you are describing is the classic poverty trap, where the benefits provided overlap with the lowest paid jobs. The usual way to get around this is to continue paying a significant percentage of the benefits for the first couple of years after the person returns to work.
The poverty trap becomes more pernicious in a low wage economy. The Welfare State attempts to provide every person with a basic income that will meet their minimum needs. If that's all a full time job will do then I can sympathise with someone for not wanting to take such a job. IMO, in our modern consumer-economy,the purpose of a full-time job is to be able to meet your basic need and
save some money for other stuff. When Unions and other protections for workers have been totally eroded, and when the race for the bottom gets into full swing, I am an advocate of the State intervening so that its citizens do not have to be at the complete mercy of business.
The globalised economy we live in means that certain jobs that people would have been qualified to do are all gone East, forcing such people to work for the minimum wage, is, IMO, unfair and a consequence of forces over which they have no control. If you allow business to make all the rules then it is only a matter of time before we return to a form of wage slavery. The Welfare State is a buttress against that, and also one that we as citizens actually can influence every four years or so.
