For prices specifically I think it's fair to say that inflation only goes in one direction, but for larger market trends, IMO the key here is _habit building_.

Many things were technically feasible pre-pandemic but not done habitually: remote work, streaming movies instead of going to the theater, ordering delivery instead of dining out, and so on. The pandemic forced many people to change their habits and get over any initial inertia (e.g. investing in a WFH setup or home theater). The result is that when the world returned to normal, the markets didn't: consumer habits had already moved on.
