There's no such thing as normal. The 70s weren't normal what with the oil embargos and stagflation and the end of the Vietnam war. The 80s had banking crises and the beginning of Reaganomics. In the 90s, computers were really beginning to eat the world and geopolitics were realigning with the end of the USSR. The 2000s surely weren't normal—the dotcom bubble burst, 9/11 kicked off wars, the housing market imploded, etc. 2010s had really bizarrely low sustained interest rates. 2020s kicked off with some unusually stringent travel restrictions worldwide and a massive uptick in remote work.
