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.
Sekarang coba bayangkan Anda adalah seorang ahli ekonomi di tahun 1929, sedang mencoba untuk memprediksi pertumbuhan ekonomi Amerika tanpa mengetahui bahwa ekonomi Amerika akan segera jatuh. Tanpa mengetahui kita akan segera memasuki bencana ekonomi terbesar di abad ke-20.
