Yes. Stores operate on the law of supply and demand. With greater demand (hoarders), and less supply (planned disruption of the food supply chain), profiteering is the predictable end result. Throughout the past hundred years, whenever commies or socialists have taken over any country, food shortages have been prevalent either prior to (or after) the takeover. Shortages and rationing go together with leftists....like Mom and apple pie! 'Twas always so.
"By destroying the peasant economy and driving the peasant from the country to the town, the famine creates a proletariat...furthermore the famine can and should be a progressive factor not only economically." Lenin
