Consistently and uninterruptedly continued inflation must eventually lead to collapse. The purchasing power of money will fall lower and lower, until it eventually disappears altogether. It is true that an endless process of depredation can be imagined. We can imagine the purchasing power of money getting continually lower without ever disappearing altogether, and prices getting continually higher without it ever becoming impossible to obtain commodities in exchange for notes. Eventually this would lead to a situation in which even retail transactions were in terms of millions and billions and even higher figures; bu t the monetary system itself would remain. But such an imaginary state of affairs is hardly within the bounds of possibility. In the long run, a money which continually fell in value would have no commercial utility. It could not be used as a standard of deferred payments. For all transactions in which commodities or services were not exchanged for cash, another medium would have to be sought. In fact, a money that is continually depreciating becomes useless even for cash transactions. Everybody attempts to minimize his cash reserves, which are a source of continual loss.
