Why would an economist ever look on the bright side?

The country is experiencing the fastest economic rebound in at least a generation, but Wall Street and Washington are hardly taking a victory lap. In any other environment, the 6.3% pace of expansion economists have penciled in for the United States this year would represent a victory. They do acknowledge that it is a solid rebound after the shock and slump of 2020. But that doesn't stop them from fretting about every incoming piece of data and how quickly it can go from good to terrible.
