You clearly have not realized the sheer amount of food that stores throw away because it wasn’t purchased. Not because it wasn’t edible, but because it didn’t turn X profit in Y time. Dumpsters are secured and food often deliberately made inedible. Very little is ever simply donated because that would call capitalism into serious question.
That is entirely irrelevant to the discussion here. The person I am responding to is arguing that we somehow could transform into a society where nobody has to work. Not one where everybody who works today still works, but with fairer and better distribution of the produced output.
