I'm surprised too that no government has tapped into what is a valuable resource and asked or requested that anyone who is physically and mentally capable of work do so in order to pay for their benefits.
Perhaps it would be too difficult to administrate or contravene their human rights.
In theory, anyone who is both "physically and mentally capable of work" has to work, because they won't get benefits unless they fall into the category of young single mother. Once children are involved, you have an entirely different ball-game, so stopping benefits will be seized upon by the tabloids as action little short of that proposed by Hitler and his chums.
There are several issues here, and none is easy to solve. Most relate to Human rights legislation - to which we adhere - and many relate to the DFM - the Daily Mail and its slime-caked compatriots.
It's important to realise that the DFM's agenda is pro-Tory but it's also conscious that its reader-base is the very group often caught cheating on benefits. Ultimately, their aim is to make money, which they will always try to do through the routine demolition of careers, aspirations and achievements of those non-Tories in the public eye, yet even the DFM is having trouble with the latest child benefit proposals.
Finally the other problem with the suggestion that all able-bodied are required to work is practicality. If there's simply no work available, what d'you do? Put them to work building roads, perhaps? Administration after administration has tried to stem the welfare tide, yet none has succeeded. But there's one other thing it's worth thinking about. HMRC estimates indicate that Welfare and benefits are running at about £2bn per annum, while tax evasion is estimated at
£8bn per annum. Maybe we're concerned about the wrong groups of people...
