In some, not all Tory minds food banks and warm banks are a positive, they are not statist and everyone knows statism leads to Socialism. In those Tory minds that see them as positive they hark back to the days of altruism and benevolence. They allow those on the right to look charitable which for those on the Christian right affirms their faith and makes them look good in the eyes of God. They can assuage their guilt by donating a few tins of Lidl beans to a food bank and they truly believe they are helping the poor and keeping them away from the dread hand of the "nanny state"
Warm banks operate under a similar principle.
I personally think that the need for both in the 6th richest country on the planet is abhorrent. People are scared to put the heating on, I have health problems and I need to keep warm, but rarely put my heating on, I went shopping yesterday and found myself buying the cheapest brands, rummaging through the going out of date section yet still managed to spend £70 on my weekly shop that used to be about £50.
When you a Cabinet stacked with Millionaires and the richest PM to ever take office, how can they possibly understand what it is like to count pennies for a bottle of milk, they never have to decide whether to eat of heat. To them we are the undeserving poor and they would rather deflect the current crisis by blaming immigrants on dinghies, Unions and anybody else apart from themselves.
