I'll let
Ezra Klein answer you:
"A year ago, forecasters expected unemployment to be nearly 6 percent in the fourth quarter of 2020. Instead, it fell to 3.9 percent in December, driven by the largest one-year drop in unemployment in American history. Wages are high, new businesses are forming
at record rates, and poverty has fallen below its prepandemic levels. Since March 2020, Americans saved at least $2 trillion more than expected. And that’s not just a function of the rich getting richer: a JPMorgan Chase
analysis found the median household’s checking account balance was 50 percent higher in July 2021 than in the months before the pandemic.
Some of these problems reflect the Biden administration’s successes. (Read my colleague Paul Krugman for
more on this.) For all the talk of supply chain crises, many of the delays and shortages reflect unexpectedly strong demand, not a pandemic-induced breakdown in production. Supply chains are built to produce the goods that companies think will be consumed in the future. Expectations were off for 2021, in part because forecasters thought demand would slacken as people lost work and wages, in part because the fiscal response was massively larger than anyone anticipated and in part because when people couldn’t go out for meals and movies, they bought things instead. Overall spending is
more or less on its prepandemic trend, but the composition of spending has changed: Americans
purchased 18 percent more physical goods in September 2021 than in February 2020."
