It used to be considered a virtue to have stocks of food put by. Families starved in the winter if a woman was too feckless to preserve fruit, cure bacon, dry herbs, and store pulses and grains, apples and potatoes and vegetables for the months when nothing was available.
Now if you do the same thing you are called a hoarder! It is al of a piece with the way shopscut down on inventory and do last-minute ordering for their stocks and expect wholesellers to deliver at the drop of a hat. The wholesellers are doing the same thing to manufacturers so everyone is rushing about fulfilling urgent orders.
The result is that whenever there is a transport crisis or the roads are snow-blocked, the shops soon have empty shelves. That makes hoarders virtuous again - they can feed their hungry neighbours if necessary. The fable of the ant and the butterfly has a lot of truth.
Ignore anyone who says you shouldn't have a full freezer. They are butterflis. Three cheers for the ants (and for the bees who store honey when they can, for when they can't)!
