The remarkable thing was that everyone accepted the entire process, seemingly as normal as physical laws of nature, despite the fact that it was really as ethereal as a rainbow. The money did not physically exist. Even "real" money was only specially made paper printed with black ink on the front and green on the back. What backed the money was not gold or something of intrinsic value, but rather the collective belief that money had value because it had to have such value. Thus it was that the monetary system of the United States and every other country in the world was entirely an exercise in psychology, a thing of the mind, and as a result, so was every other aspect of the American economy. If money was simply a matter of communal faith, then so was everything else. What the Federal Reserve had done that afternoon was a measured exercise in first shaking that faith and then allowing it to reestablish itself of its own accord through the minds of those who held it. Holders of that faith included the governors of the Fed, because they truly understood it all-or thought that they did. Individually they might joke that nobody really understood how it all worked, any more than any of them could explain the nature of God, but like theologians constantly trying to determine and communicate the nature of a deity, it was their job to keep things moving, to make the belief-structure real and tangible, never quite acknowledging that it all rested on nothing even as real as the paper currency they carried with them for the times when the use of a plastic credit card was inconvenient.

They were trusted, in the distant way that people trusted their clergy, to maintain the structure on which worldly faith always depended, proclaiming the reality of something that could not be seen, an edifice whose physical manifestations were found only in buildings of stone and the sober looks of those who worked there. And, they told themselves, it all worked. Didn't it? In many ways Wall Street was the one part of America in which Japanese citizens, especially those from Tokyo itself, felt most at home. The buildings were so tall as to deny one a look at the sky, the streets so packed that a visitor from another planet might think that yellow cabs and black limousines were the primary form of life here. People moved along the crowded, dirty sidewalks in bustling anonymity, eyes rigidly fixed forward both to show purpose and to avoid even visual contact with others who might be competitors or, more likely, were just in the way. The whole city of New York had taken its demeanor from this place, brusque, rapid, impersonal, tough in form, but not in substance. Its inhabitants told themselves that they were where the action was, and were so fixed on their individual and collective goals that they resented all the others who felt precisely the same way.
