20 years ago I was on a training course with the Benefits Agency which I worked for. Two questions came up, about where benefits money came from and the size of the budget. National Insurance is one small contributor to the fund. The money in their 'pot' actually comes from other taxes, vehicle excise duty, income tax, vat, company taxes. Not only that, but the 'official' budget level for the then BA was under reported by around 30%. As a job seeker, I get told by the DWP that the benefit paid to me is 'their' money. It is not. It is what I paid in, so to sanction someone is like you handing over your money and being told you can't have it back. Thankfully with BIG there is no need for sanctions.
