I have been hearing this new argument a lot lately and on both sides of the coin. "It's not a supply problem it's either a "not enough" or "too much" demand problem. The first time I heard it was regarding the lack of toilet paper in stores, now it's going to bankrupt farmers. I think it's actually a problem with the just in time delivery system currently being used. What 50 years ago would have been considered due diligence in having a couple months of food and consumables is now considered hoarding. Maybe the current delivery/storage system is causing these fluctuations in demand to affect the supply so drastically? Maybe it's small condos without closet pantry or freezer space in our over populated, "housing crisised" cities causing it? It's been a long time since I took a Consumer-ed / Home economics class and I don't even know if they teach it anymore (maybe it was replaced by coding classes?) but when I was in school "Supply and Demand" were tied together and you couldn't do any calculation with one and not the other let alone blame a problem on one.
