But it didn’t fall apart. I’ve been able to get nearly everything I was getting before the pandemic. Prices of some stuff has increases and there are a few things that are harder to find, but the variety of goods available to me now is still way better than it was even just 20 years ago.
The system is stunningly resilient. Shortages of a few things doesn’t mean “the whole thing falls apart”. You’ll know if that happens because people will get really violent really fast when food or water stops.
