Controversial I know but it should be abolished IMO,the welfare state should be a safety net for people in real hardship.Not for redistributing wealth.
Tin hat on,hatches battened down etc.

We are talking Tax Credit, NOT Working Tax Credit. I am no expert, but as I understand it there used to be a bit of income tax relief for children, this has now been replaced with Tax Credit, a totally Crap system who's failure has caused real hardship for some families. I know of a family who were given £14,000 in tax credit cos someone put the decimal point in the wrong place, this family were aware enough to know there was a mistake and did not spend the money, it took them many phone calls over about 9 months before the tax credit people accepted a mistake and took the money back. I could go on, but can't be bothered at this time of night. Crap system, and find me a CAB or welfare rights organisation that disagrees with me, and as we say ' I will show my ares in Binns window'......
