196 INDUSTRIAL REVOLUTION AND WAGES 
which has distinctly characterized the post-war period. 
The stupendous industrial effort put forth during the 
World War taught the great value of cooperation, coor- 
dination, and mass effort. The enlightened constructive 
policy which was finally adopted after the breakdown in 
1920-1921, and its two-year wake of depression—a pro- 
gram which conceded an indeterminate advance in wages, 
provided productivity was increased and costs reduced— 
has practically produced an American industrial revolution 
of epoch-marking significance. Its results have attracted 
world-wide comment and study. The leading industrial 
nations have sent special commissions to the United States 
to study the secrets of American accomplishment. Un- 
doubtedly the policies which were inaugurated here in 
1923 will in time revolutionize industrial methods and 
performance throughout the world. 
CoMPARISON OF USE oF POWER AND RELATIVE EMPLOYEE 
PropucTiviTY IN GREAT BRITAIN AND THE 
UNITED STATES 
The importance of the use of power and mass produc- 
tion in the United States as compared with Great Britain 
was very forcibly brought to light in a study recently made 
by the National Industrial Conference Board.? The Board 
showed the following summary of the facts developed:

manufacturing per wage-earner for each of the eight indus- 
tries compared in the two countries are given in the following 
table, data for Great Britain referring to the year 1924, 
those for the United States to the year 1925:
