Indeed they do but you've cast the net so wide that like i said you've made it all but impossible to verify your claim, is it unemployment, income support, tax credits, housing, sickness benefit, fraud, or the financial costs involved?
Well unless you can provide some evidence other than because i worked there and i said so then it is a false claim as all the evidence I've looked at say's you're not only wrong on the costs of sickness benefits but also the percentage of outright fraudulent, or 'heavily over-embellished' claims.
I mean the total social security expenditure for 2014/15 was £258 billion and you're claiming that £215 billion of that is made up of people claiming sickness benefits, call me skeptical but i highly doubt all other social security expenditure only amounts to £43 billion, pensions alone make up £108 billion.
No it's not, estimated fraud accounted for approximately £1.2 billion and while that may sound like a big number it's not as *over payments during the same period were almost double that figure.
And no that figures does not include fraudulent payments recovered, balancing the books, or anything else, it's an estimate and without you providing any information to backup your claims that's all we have to go on.
Like i said before the amount of "fraud" in the social security system is estimated to be very small, no system is perfect, however when you compare it to the TAX system the numbers pale in comparison, HMRC estimated the tax shortfall to be £36bn in 2014/15 and most people say they've massively underestimated that figure as we have the lowest percentage of tax shortfall in the entire world, less conservative estimates put the UK's tax shortfall somewhere between £65 billion to £160 billion.
