John Kenneth Galbraith wrote this in 1954, in his book The Great Crash, and it still rings true today:
In the autumn of 1929 the mightiest of Americans were, for a brief time, revealed as human beings. Like most humans, most of the time, they did some very foolish things. On the whole, the greater the earlier reputation for omniscience, the more serene the previous idiocy, the greater the foolishness now exposed. Things that in other times were concealed by a heavy façade of dignity now stood exposed, for the panic suddenly, almost obscenely, snatched this façade away. We are seldom vouchsafed a glance behind this barrier; in our society the counterpart of the Kremlin walls is the thickly stuffed shirt.
