The fact is, said Cyril, you can only understand any percentage if you ask “... of what?”
So let's just apply the Cyril test to the concept of fairness proposed by the government.
Let's imagine you're a cabinet minister with an income of £134,565. You spend modestly on heating and food every year and “fair” austerity conditions are applied to you — a 1% pay rise every year, in the face of 4% rises in basics. This year you spend £14,000 on food and heating (bear in mind you have more than one property to heat) with £120,565 for everything else, including tax. After five years your income is £140,028, and Inflation has raised your spending on food and heat to £16,378. This leaves £123, 650 for everything else — actually, just over a 2% rise in spending money! O Joy! And if that's not enough, you can easily increase your earnings with non-exec directorships and other casual earnings.
Let’s apply the same calculation to a single parent on minimum wage with two children and top up benefits. This produces £12,000 a year, of which she spends £1,100 on heat and £7,800 on food. This leaves £3,100 for everything else. Now apply “fairness.” After five years she has £12,487 of income, spending, £10,411 for essentials, leaving £2,075 for everything else. Oh dear. That’s a cut of 30% in money available for everything else.
Finally, consider a pensioner couple with a very small private pension funded from savings. Now they live on £8,000 a year, spending £750 on heating and £2,800 on food. This leaves £4,550 for the rest, including rent. Let’s apply a bit of “fairness.” After five years on the same assumptions, their income is £8,324, with £877 to spend on heating and £3,275 on food. This leaves £4,171 for everything else, a 10% cut.
So, right off the back of the envelope, fair is fair. But it's a lot more fair if you're a Tory minister where tightening the belt involves limiting yourself to a 2% rise in spending money. It’s less fair if you're a pensioner couple facing a 10% cut, or a mother of two facing a 30% cut. Of course it will affect your children. How could it not?
The reasons bishops have said what they have is Maths, not Marxism. Go figure. I'd love to see a better model than the back of my envelope including housing costs, if anyone out there knows of one...
As to the feckless poor hypothesis, kudos to the Methodist, Baptist and United Reformed Churches for producing a report, the Lies we tell ourselves that introduces a note of reality to the discussion.
