Every legitimate form of insurance exhibits substantially the same characteristics; it reduces loss at the margin where it is felt most keenly. The difference between insurance and gambling, thus, lies primarily in the purpose of insurance, which is not to increase artificially the risk that any individual runs, but to neutralize or offset an already existing chance. The insurance bet is what is called a "hedge." The difference lies further in the collective method of insurance, which combines the chances scattered among a number of persons. Insurance does not increase the total of risks and of losses, but merely combines, averages, and distributes them equally among all the insured. This eliminates the chance element to the individual by converting it into a regular cost. § 6. #Insurance as mutual protection.# Modern insurance is conducted either by enterprisers for profit, or by mutual companies; but in any case in large measure the losses in insurance are mutually shared, as the premiums (plus interest earned) equal the total losses plus operating expenses and profit, if any is made. Each insured gets a contract of indemnity for the payment of a sum that will help cover the losses of others. Such an exchange is mutually beneficial. The premium comes from marginal income; the loss if it occurs would fall upon the parts of income having higher value to the insured. The less urgent needs of the present are sacrificed in order to protect the income that gratifies the more urgent needs of the future. In insurance each party gives a smaller value for a greater; each makes a gain. The greater security in business stimulates effort. This effect is quite the opposite of that of gambling.
