Why do people get this impression a pandemic, combined with an unprecedented economic drawdown, combined with one of the most vitriolic political climates we've ever seen is just going to "blow over", and in 6 months we'll be going along like nothing ever happened?

Covid19 might go away (or it might not, there's always that). But many things are going to change. Who's to say we don't now decide that cruise ships are a stupid idea, because they spread disease, pollute like crazy, don't pay taxes and need bailouts? Many industries disappear.
