0.796% of the UK population goes a food bank. It's not at all nice or good - but compare this to the 1.6 million in Spain who have relied on handouts from the Red Cross:
What we don't know is how many of those relying on food banks do so because of poor budgeting. How many have multiple vehicles, Sky/Virgin etc for example? How many go to the pub or smoke? When I lived in Milton Keynes I knew a couple with 2 kids who regularly went to the food bank, yet they had a huge TV, several computers and consoles, both smoked and both went to the pub at least once a week.
That suggests to me that actually (based on what I saw), the issue isn't evil Tories, but poor budgeting. And that suggests vouchers for food rather than cash benefit payments is the way forwards.
