Editorial note — Chapter I

Hence Engel thinks that when the articles of food, clothing, shelter, heating and lighting have become dearer by 50 per cent., and other wants have not, and it is desired to proportionately increase the salaries of officials, salaries of 300, 600 and 1,000 thalers should be raised to 427.5, 800 and 1,275 thalers respectively. (Preuss. Statist. Zeitschr., 1875.) E. Herrmann, Pricipien der Wirthsch., 106, estimates that in all Europe, 45.6 of all consumption is for food, 13.2 for clothing, 5.7 for shelter, 4.6 for furnishing, 5.3 for heating and lighting, 2.6 for tools and utensils, 13.3 for public security, 6.6 for purposes of recreation. Compare Leplay, Les Ouvriers Européens, 1855, and v. Prittwitz, Kunst reich zu werden, 487 ff. The expenses for shelter, service and sociability are specially apt to increase with an increase of income.
