"There are other places in the country to live rather than the SE although you wouldn't think so if you read some of those threads."
So, if it was me having to claim housing benefit (it's not, but anyway), it'd be better for me to take my children out of their outstanding OFSTED rated school, and move to an area where there are very few jobs and where wages are massively lower. Because it's these areas where housing costs tend to be lowest. It'd also be reasonable to expect me to leave behind both mine and DH's elderly and infirm parents who currently live nearby and tell them to shift for themselves?
You really think it's reasonable to remove people from their communities, take them away from their support systems and family networks, uproot their children from school, make it more difficult for them to find permanent, well-paid work, to save money on housing benefits?
"They can start at the bottom on the grottiest tiny bed sit they can like most of us have had to do in the nether reaches of the worst bit of town and work their way up.. but no... they need to have that designer 4 bed whether rented or not."
What are you talking about? Whole families in a tiny bedsit? Who gets a 'designer 4 bed home' on housing benefit? Round here £800 would pay for a small 2 bed flat in one of the grimmer parts of outer London.
Anyway, you're going to get your wish about poor people claiming housing benefit being removed from central London. Apparently some schools are losing up to a third of their pupils as the hard up families are uprooted from their communities and sent to live in cheaper areas. Hey ho, I know if it was me and my children I'd be utterly devastated, but if it means we can carry on paying rich pensioners their fuel allowance then it's got to be worth the distress and upheaval it'll cause to some of the most disadvantaged families in the country.
Rock on Thatcher's children!
