At a low level, it appears as a way of topping up meagre salaries.
I am now aware of a whole new dimension of corruption which I find morally offensive. I have discovered that council employees are paid bonuses according to how much benefit they can avoid paying out to claimants that are entitled. The level of these bonuses is such that said council officials can go out and buy a new car or put down a mortgage on a house. So, those who have no advocates who can fill in the forms and write letters the way that ticks the right boxes are denied money that they need. We are not talking about benefit fraud here; this is denying hard-working families money to food in their children's mouths. So, instead of helping those that need it, the council employees are lining their own pockets.
So, you ask where is this corruption to be found? Well it's NOT Spain. It's in the UK! The so-called bastion of fair play has stooped to the lowest form of moral corruption whereby money is withheld from the most vulnerable and defenceless.
If you want to get benefit in the UK you need an advocate to fight for you. This is why certain groups are so successful at getting it. They have the systems in place to get it for them; and good luck to them. I shall be putting this to my MP with a view to having the "civil servant" who invented this scheme forced to apologise to every failed genuine claimant for the rest of their lives!
