The lack of empathy on mumsnet, as always, is stupefying and the profound misunderstanding about what is actually going on is mystifying.
The under-occupancy rules mean that only social housing tenants are required to move or pay more. In many cases, as there is a lack of social housing, they end up in the private sector and receive more in H.B than they would have been using in social housing with its protected rents. Thus public money is paid into private hands and the expenditure actually rises.
The misery that is being inflicted on individuals as part of a political ideology is extremely unfair. This is not about deficit reduction, as in the end it doesn't actually save money. In fact many of the budget cuts aren't really about deficit reduction, if the government were really about that they wouldn't be cutting taxes for the wealthiest and for corporations, they may have looked at means testing benefits for the retired.
But no they will hit the poor and vulnerable, and many people will encourage them, spurred on by the media who misinform and pull the debate in the way that suits their own interests.
The facts, as I've oft repeated, show that cutting benefits does not cut the deficit, but believe what you like, and sit comfortable in your own home congratulating yourself on how your hard work is rewarded, when much of it really is down to good fortune.
"As long as the general population is passive, apathetic, diverted to consumerism or hatred of the vulnerable, then the powerful can do as they please, and those who survive will be left to contemplate the outcome." Noam Chomsky
