Though a couple both on jobseeker's allowance just about make 40% of the average British household income, a single person doesn't. £67.50 per week is a mere 34% of a single person household's average income. Maybe the single unemployed ought to give up their computers, their link to the outside world, so they can have a healthier diet. Yes, that's what they should do.
But once again the poverty experts make a minimum standard of living sound so luxurious that policy makers are not going to take them seriously.
The Joseph Rowntree Foundation commissioned a survey of the great British public to ask them what they think people need to reach a minimum standard of living.
You can do the questionnaire here and it basically says that after rent, mortgage interest, council tax, buildings insurance and water charges, a single person needs £163 per week or 82% of average income to maintain a minimum standard of living. A couple would need £259 or 76% of a couple's average income.
The public doing the survey were asked what the minimum should be that nobody should fall below. I don't know whether they were then asked what the level of jobseeker's allowance should be. I doubt it.
