Hoover put too much trust in the wisdom of American voters.
Because he taxed the middle and lower class too much and it made things worse.
Yes Congress has relinquished too much power to the President.
It came too quickly.
Well, Hoover was in office when the Great depression developed, 1929 - 1931, but if we're going to blame individuals for global financial disasters, we have to look too at Coolidge as well. Hoover didn't fix it, but he only took the office in March of '29. Hoover was also president October 1929 when the stock market crashed, but it's high unlikely (impossible) that anything he did lead to the crisis.
Too much
Trust me, he has too much to fit on this page...
President Hoover believed in limited government intervention in the economy and thought that the economy would naturally recover on its own. He was also concerned about the potential for increased government spending and debt. Additionally, Hoover believed that direct relief to the unemployed could discourage them from seeking work. He did implement some limited measures, such as creating the Reconstruction Finance Corporation, but these efforts were criticized as being too little and too late.
He drank too much.
Too much
HOOVER ---- Actually Hoover for the begining of it for overreaction with too much spending. Then FDR for extending it and prolonging it with even more spending. Even FDR himself stated portions of his NEWDEAL was a failure (specificially as it related to unemployment, since most of his work programs were not jobs, but just 'make work' and some were not even with pay. Hoover helped the depresssion along by doing the tarrifs and etc which turned it into a full depression... Till that, it was still more of a major crash. Fact is, that Hoovers predesssors created the best economic times ever, and by overspending and then overreacting, the depression was not only created but deepened. Hoover actually deserves blame but so does FDR for too much followup. FDR himself stated in 1939 that they overdid portions of the response and it was those responses that extended the depression.
When you trust others you feel freer. However, placing too much trust in others may set you up to be taken advantage of by others.
Trust could unfairly raise prices since they had no competition
