108. Since the terrestrial human community alone and not single individuals or companies can possess the valuable goods, the world economy will become perfected, and so, in the World State, it will not be permitted for one part of the world to burn and destroy its overproduction of necessities of life because the poverty-stricken population in another part cannot afford to pay the rate of exchange fixed by credit companies and business magnates, or cover the charges connected with the consignment or export of goods. In all respects, the surplus production of the fertile countries will be used to benefit the underproductive countries. Customs duties between countries will be abolished and the customs services will be changed over to serve as units in the economy's police control of the world domain. That is, they will be given the task of keeping the world government informed as to the financial situation, the surplus production and under production of each country and will thus become a fundamental support for the whole world regulation of the economy.
