Actually there is a real residential toilet paper shortage that would exist even if no-one was hoarding. In normal times, half the toilet paper used is at work or some other commercial establishment outside the home. It turns out that toilet paper has a completely different supply chain and comes in a completely different form, mainly large rolls. And it's not easy to switch overnight. In fact one of the biggest suppliers for the commercial market doesn't even sell at all to the residential market.Mass behavior like in stock markets and like people buying huge amounts of toiletpaper.
Proof that they understand nothing and react because their neighbor reacts.
So we have plenty of toilet paper, it's just in big commercial rolls. You can actually back this up by going to Amazon, you can buy as many of those big rolls as you want today. We just don't have enough residential toilet paper, because we're using nearly twice as much of it as we were, and the switch happened literally overnight.
Perhaps proof that often the "obvious" answer isn't the right answer, and digging a little deeper when you see something irrational is a better path then assuming the worst about our fellow man.
