Hoover blames WWI for global depression, but Green explands that it’s a little more complicated that that. Hoover did the after-effects of the war really impact world finances?

Do you have more info about it ? i doubt this is the answer because i don't have all the information but if trouble was brewing in a clinic maybe it was an argument as to which clinic was better or smth of that nature

Yes, some people used the depression to the max. not everybody had stocks, and those that didn't bought many things inexpensive, so that when prices rose again, they were much more richer than beforehope this
