In my local co-op a while ago I saw two normal guys getting stuff out the bin at the side but they looked normal not homeless or destitute so started chatting to em. They said they just took it coz the stuff is still fine and the shop has to throw it away due to sell by date but is still edable for at least a week or so. They said it was amazing how much they took out bags full and the shop was alright with it. The main problem is food waste if they could combat that there would be ample food for everyone noone need go hungry but big cooperation just don't care coz there is no money in it all about profit
We have some schemes here where expired food goes to shelters and, I believe, a kitchen that provides free or low-cost meals. It could be better organised so that no food is wasted, perhaps a tax for waste? I agree there's enough food, and enough money to pay for food, but it is not distributed so that everyone has enough.
