I'll go you one better;<quoted text> Here I'll type this real slow for you so you can understand! Type in 'wheat prices caused great depression'. Pick one, open it, and read.
Not a one mentions wheat. When I did the search you mentioned, it produced nothing connected to wheat as the reason.
Here's what your search turned up;
"The Great Depression was the worst economic slump ever in U.S.
history, and one which spread to virtually all of the industrialized
world. The depression began in late 1929 and lasted for about a
decade. Many factors played a role in bringing about the depression;
however, the main cause for the Great Depression was the combination
of the greatly unequal distribution of wealth throughout the 1920's,
and the extensive stock market speculation that took place during the
latter part that same decade. The maldistribution of wealth in the
1920's existed on many levels. Money was distributed disparately
between the rich and the middle-class, between industry and
agriculture within the United States, and between the U.S. and Europe.
This imbalance of wealth created an unstable economy. The excessive
speculation in the late 1920's kept the stock market artificially
high, but eventually lead to large market crashes. These market
crashes, combined with the maldistribution of wealth, caused the
American economy to capsize."
Unequal distribution of wealth, buying on margin, Pres. Hoover's ineptness were the primary causes of the Depression.
The wheat thing is so stupid, only nitwits like you would believe it.
