I’ve heard this before - That what happened was people there began taking out their own food and sharing it, which is how everyone got fed.
I hadn’t heard it in a socialist context, but in one where the proponent of this idea didn’t believe in miracles.
It’s interesting to note that, yes, this is a very socialist fairy tale. That there’d be enough for everyone if the haves decided to share with the have-nots.
But, that’s not how it really happened!
