You rotten, unbelievably vicious and vindictive fucking fellaters of the self-pitying super-rich. Seriously, you absolute dried out pillars of loathsome scum. Do you think anyone living on or around £13,000 a year who goes on strike is doing so out of some sort of old-fashioned Northern accented, Fred Kite-style perverse desire to put a broom in the wheels of industry just for the sake of being bloodyminded? Would a glassy-eyed Tory ideologue like Ian Duncan-Smith even know how to get by on that sort of money? Does it not cross his mind, long since ossified by dogma, that industrial action is the last, desperate resort of working people being priced out of existence by you moneysucking cunts, as opposed to having a jolly at the expense of the taxpayer? God, this government is detestable beyond belief.

Duncan Smith said that families living on benefits, and very wealthy families, were more likely to have large numbers of children than families on average incomes. That was because families on average incomes had to decide how many children they could afford, he said. Families living on benefits should be forced to make the same decisions, he said.

Duncan Smith appears to be conflating the idea of worklessness with payments for children. If that is the case then he will not be saving much money with this measure: just 4% of families on jobseeker's allowance have more than two children. Say each child gets roughly £65 a week – about £50 from child tax credits and the rest in child benefits – then the savings are about £300m a year. In fact they would be much lower, as half the people on jobseeker's allowance get work within six months.

Now consider that Duncan Smith is trying to save £10bn a year. To make this magnitude of savings the government would have to look at the 2 million children in the 584,000 working families with more than two children who get child tax credits. These are people who are in low-paid jobs struggling to make ends meet. There are another 880,000 working families with more than two children receiving child benefit, with around 2.9 million children affected.

Child tax credits are means-tested but the Children's Society calculates that the saving on them, if they were restricted to taking a maximum of two children into account, would be about £3.5bn a year. Savings on child benefit, if reshaped in a similar way, would yield up to £1bn. This is big money.
