There are two kinds of forecasters: those who don’t know, and those who don’t know they don’t know. - John Kenneth Galbraith

The individual serves the planning system not by supplying it with savings and the resulting capital; he serves it far more by consuming its products. On no other activity, religious, political or moral, is he so elaborately, skillfully and expensively instructed.

This view that the action of the Federal Reserve authorities in 1927 was responsible for the speculation and collapse which followed has never been seriously shaken. There are reasons why it is attractive. It is simple, and it exonerates both the American people and the economic system from substantial blame... Yet the explanation obviously assumes that people will always speculate if only they can get the money to finance it. Nothing could be farther from the case. There were times before and there has been long periods since when credit was plentiful and cheap—far cheaper than in 1927-29—and when speculation was negligible. Nor was speculation out of control after 1927, except that it was beyond the reach of men who did not want in the least to control it. The explanation is a tribute only to a recurrent preference, in economic matters, for formidable nonsense.

However, none of this was immediately apparent. If one has been a financial genius, faith in one’s genius does not dissolve at once. To the battered but unbowed genius, support of the stock of one’s own company still seemed a bold, imaginative, and effective course. Indeed, it seemed the only alternative to slow but certain death. So to the extent that their cash resources allowed, the managements of the trusts chose faster, though equally certain death. They bought their own worthless stock. Men have been swindled by other men on many occasions. The autumn of 1929 was, perhaps, the first occasion when men succeeded on a large scale in swindling themselves.
