Elderly people may not pay NI now but most of us paid an awful lot during our working life. I agree about closing tax loopholes and also stopping some capital project like HS2 but NI and tax will undoubtedly have to increase and providing it has a reasonable starting point then people like my daughters would not mind paying a bit more.By the way no one who earns over £50k gets child benefit.
It might say you are eligible but it effects your tax and only becomes viable if you can prove you have more expenses relating to your job than the child benefit provides. I suppose if your millionaire is self employed then he could fiddle it but for anyone who pays PAYE then its basically a no no.
There are far more old people than there used to be, and the number is likely to continue rising.Everyone has to pay, pensioners can no longer say we have paid all our lives, why should we pay now [ I speak as someone in receipt of a pension ]Progressive taxation seems the only fair way to me, and far stiffer penalties for tax evasion.
