This is an excerpt from Paper Promises: Debt, Money and the New World Order, published this week by PublicAffairs.
Consumers have always borrowed money from friends, neighbors and relatives. Merchants would not exist without credit; the habit of making debts on a “slate” in the local butcher or greengrocer was still common in the middle of the twentieth century. But the local merchant would normally offer credit only to a known, local customer; serial defaulters, or those deemed to be untrustworthy, would be refused business. In David Copperfield, Mr. Micawber’s failure to repay merchants required him to cadge off his friends.
But the modern idea of widespread consumer credit (in the form of national lenders, credit cards, etc.) really dates to the Industrial Age. A peasant’s income is unlikely to grow over the long term; at best, it will be highly variable, with bumper harvests in good years giving the peasant sufficient income to pay off debt incurred in bad years. But two or three bad harvests in a row could be ruinous.
This point illustrates a wider truth. The granting of a loan requires both the creditor and the debtor to be confident that the latter’s income will grow sufficiently to repay the debt. Think of a retailer that sells a washing machine, or television, in installments. Clearly the customer does not have the money now; otherwise he or she would pay upfront. Moreover, the overall bill, including interest, will be greater than the cash price. So the debtor must be confident that he will stay in employment to pay the larger sum. In addition, he or she will probably be confident that their future income will rise so as to offset the additional interest. A growing economy makes that calculation all the more likely.
The Industrial Revolution changed the pattern of human civilization. It allowed economic growth to expand at a much faster rate than ever seen before. This was probably down to the use of carbon-based fuels (wood, coal and, eventually, oil) to power technologies to replace human and animal labor. This resulted in a substantial increase in productivity.
