...forget how poor the poor truly are: the least affluent 10% have a disposable income of less than £90/week. So for them an additional £20/week would be no small windfall.
But can this be true? The IDS proposal is a transferable personal allowance. So the receiver gains 20% on just over £5k a year, which works out at £10/week. However to gain this surely you need to earn two personal allowances - more than £200/week.
