I don't really like having reductions now which I know I wil have to repay later, as I don't work that way in my private finance, but I have complete faith in Gordon Brown as he has always seemed to know what he is doing.
Wait until you see your income tax bill rise in a couple of years time when all the country's debts for excessive borrowing have to be repaid and then you'll be able to answer your own question as to whether he got it right or not.
