>>>GDP has long been criticized for being a poor metric for the economy. But it's always been correlated enough with overall economic sentiment that it was Good Enough.

Huh?

Discussing the utility of and then issues with GDP has been a staple of Macro courses for decades. E.g., [1], but I'm really serious: every single macro textbook for as long as macro textbooks have existed has had some version of the question "Discuss the strengths and weaknesses (i.e., problems) of using GDP data".
