What is one way in which other countries contributed to the great depression in the u. s

The other capitalist countries in the world all suffered from the same malaise of the US the typical boom or bust cycles that typify capitalism except in the case of the Great Depression the consequences were very drastic. The effect of other industrialized countries on the US Depression was partly from drastically decreased trade and purchase of US goods. Trade of Britain, France and Germany dropped 54-61% and industrial production in those 3 countries dropped 23-41% and this definitely affecfted the US which experienced a 70% drop in trade then.

The answer is Great Britain and Germany. Both suffered and was in debt to the US during the Great Depression because of the war. Germany has great debts with the US, it needs to pay for the reconstruction for repatriations to European countries that won. But when the Great Depression arrived, the US bank wanted Germany to pay its loan which made the German banks breakdown. 

Its a whole new world
