Prosperity having increased, another factor commences to assert itself. The spirit of economy and thrift which had prevailed throughout the years of depression gives place to extravagance, the demand for luxuries, and other unproductive forms of expenditure. While the total production is much greater than in the lean years, the margin of production is not proportionately as great, and this amount is insufficient to meet the demands upon it. The supplies of liquid capital stored up during the years of depression are resorted to, and they serve to provide the new capital for a few additional years. Interest rates at once reflect the encroachment upon stored-up capital, and their rise gives the first real warning of the country's true position. The optimistic business men do not heed the warning. After exhausting all the real capital available in the country, they proceed to borrow extensively from foreigners or from government banks--in this country from the national government through bank deposits. Every step which can be taken to induce foreigners to part with their capital is resorted to. If foreigners will not buy long-term bonds, short-term notes are created. If the foreigners refuse these, they are asked to make loans secured by the new bonds and notes. The rates of interest offered are so attractive that considerable sums are usually obtained, and the pressure of business activity continues further. Finally the day of reckoning arrives when some incident, usually unimportant in itself, first suggests to the lenders of money that their debtors whom they know to be overextended may not be able to pay their loans. The attempt to collect their loans produces a financial crisis which brings to an end the period of prosperity. The foregoing is a description of the more important stages through which business conditions pass from crisis to crisis. Different cycles vary in particular details, but all agree in essential outlines. Sometimes special influences are at work which operate to shorten or prolong the cycle. The approach of a crisis will be retarded by inflation of the currency, for the excess finds its way into bank vaults and increases the volume of loanable credit. The effect of such inflation, however, is wholly disastrous, because the addition to the supply of capital is fictitious, not real, and only defers the day of reckoning for a greater catastrophe. On the other hand, the approach of a crisis can be greatly hastened by wars, conflagrations, and other agencies which destroy capital, and by attacks upon capital and the conduct of corporate business, for such attacks tend to render capital timid and produce the same effect as a violent curtailment of the supply. These are only some of the many influences which might become operative, but they serve to show the necessity for careful consideration of all the factors at work if a true conception of the condition and tendencies of business is to be formed.
