Now let's imagine that you were an economist in 1929, trying to forecast future growth for the United States, not knowing that the economy was about to go off a cliff, not knowing that we were about to enter the greatest economic disaster certainly in the 20th century.
Imaginez que vous étiez, en 1929, un économiste qui tente de prédire la croissance future aux États-Unis, ignorant que l'économie était au bord de la falaise. Sans savoir que ce qui vous attendait, c'était le pire désastre économique du vingtième siècle.
