Betsey Stevenson, NPR Marketplace: "I think it’s a reflection of an ongoing need to move back towards an economy that looks a little bit more like 2019. In terms of the mix of the types of goods and services that people buy."
In other words, too many people work in the goods-producing sector, and not enough in services. Stevenson said the more people switch jobs, the greater the odds anybody can find a better one.
