Human behaviour is what drives economics, not computer models, and human behaviour hasn't changed in a very long time.
"Gentlemen, I have had men watching you for a long time and I am convinced that you have used the funds of the bank to speculate in the breadstuffs of the country. When you won, you divided the profits amongst you, and when you lost, you charged it to the bank. You tell me that if I take the deposits from the bank and annul its charter, I shall ruin ten thousand families. That may be true, gentlemen, but that is your sin! Should I let you go on, you will ruin fifty thousand families, and that would be my sin! You are a den of vipers and thieves."
~ Andrew Jackson, 1767-1845, 7th US President, when forcing the closure of the Second Bank of the US in 1836 by revoking its charter.
And part of his farewell speech.
"... It was not easy for men engaged in the ordinary pursuits of business, whose attention had not been particularly drawn to the subject, to foresee all the consequences of a currency exclusively of paper; and we ought not, on that account, to be surprised at the facility with which laws were obtained to carry into effect the paper system. Honest and even enlightened men are sometimes misled by the specious and plausible statements of the designing. But experience has now proved the mischiefs and dangers of a paper currency, and it rests with you to determine whether the proper remedy shall be applied.
The paper system being founded on public confidence and having of itself no intrinsic value, it is liable to great and sudden fluctuations, thereby rendering property insecure and the wages of labor unsteady and uncertain. The corporations which create the paper money cannot be relied upon to keep the circulating medium uniform in amount. In times of prosperity, when confidence is high, they are tempted by the prospect of gain or by the influence of those who hope to profit by it to extend their issues of paper beyond the bounds of discretion and the reasonable demands of business. And when these issues have been pushed on from day to day until the public confidence is at length shaken, then a reaction takes place, and they immediately withdraw the credits they have given; suddenly curtail their issues; and produce an unexpected and ruinous contraction of the circulating medium which is felt by the whole community.
The banks, by this means, save themselves, and the mischievous consequences of their imprudence or cupidity are visited upon the public. Nor does the evil stop here. These ebbs and flows in the currency and these indiscreet extensions of credit naturally engender a spirit of speculation injurious to the habits and character of the people. We have already seen its effects in the wild spirit of speculation in the public lands and various kinds of stock which, within the last year or two, seized upon such a multitude of our citizens and threatened to pervade all classes of society and to withdraw their attention from the sober pursuits of honest industry. It is not by encouraging this spirit that we shall best preserve public virtue and promote the true interests of our country.
But if your currency continues as exclusively paper as it now is, it will foster this eager desire to amass wealth without labor; it will multiply the number of dependents on bank accommodations and bank favors; the temptation to obtain money at any sacrifice will become stronger and stronger, and inevitably lead to corruption which will find its way into your public councils and destroy, at no distant day, the purity of your government."
