Nothing to fear...
we've been here before.

...the rulers of the exchange of mankind's goods have failed through their own stubborness and their own incompetence, have admitted their failure and abdicated. Practices of the unscrupulous money changers stand indicted in the court of public opinion, rejected by the hearts of men.
True, they have tried, but their efforts have been cast in the pattern of an outworn tradition. faced by failure of credit, they have proposed only the lending of more money.
Stripped of the lure of profit with which to induce our people to follow their false leadership, they have resorted to exhortations, pleading tearfully for restored confidence. They know only the rules of a generation of self-seekers.
They have no vision and when there is no vision the people perish.
The money changers have fled from their high seats in the temple of our civilization. We may now restore that temple to the ancient truths. The measure of the restoration lies in the extent to which he apply social values more noble than monetary profit. Happiness lies not in the pursuit of money; it lies in the joy of achievement, in the thrill of creative effort.
-Franklin D. Roosevelt, 1933: First Inaugural Address
