<P> Samuel Gompers, head of the AFL, and nearly all labor unions were strong supporters of the war effort . They minimized strikes as wages soared and full employment was reached . The AFL unions strongly encouraged their young men to enlist in the military, and fiercely opposed efforts to reduce recruiting and slow war production by the anti-war labor union called the Industrial Workers of the World (IWW) and also left - wing Socialists . President Wilson appointed Gompers to the powerful Council of National Defense, where he set up the War Committee on Labor . The AFL membership soared to 2.4 million in 1917 . In 1919, the Union tried to make their gains permanent and called a series of major strikes in meat, steel and other industries . The strikes, all of which failed, forced unions back to their position around 1910 . </P> <P> While Germany rapidly mobilized its soldiers, it had to improvise the mobilization of the civilian economy for the war effort . It was severely handicapped by the British blockade that cut off food supplies, machinery and raw materials . </P> <P> Walter Rathenau played the key role in convincing the War Ministry to set up the War Raw Materials Department (Kriegsrohstoffabteilung--"KRA"); he was in charge of it from August 1914 to March 1915 and established the basic policies and procedures . His senior staff were on loan from industry . KRA focused on raw materials threatened by the British blockade, as well as supplies from occupied Belgium and France . It set prices and regulated the distribution to vital war industries . It began the development of ersatz raw materials . KRA suffered many inefficiencies caused by the complexity and selfishness KRA encountered from commerce, industry, and the government . Some two dozen additional agencies were created dealing with specific products; the agencies could confiscate supplies and redirect them to the munitions factories . Cartels were created and small firms merged into larger ones for greater efficiency and ease of central control . </P> <P> The military took an increasingly dominant role in setting economic priorities and in direct control of vital industries . It was usually inefficient, but it performed very well in aircraft . The army set prices and wages, gave out draft exemptions, guaranteed the supply of credit and raw materials, limited patent rights, and supervised management--labor relationships . The industry expanded very rapidly with high quality products and many innovations, and paid wages well above the norm for skilled workers . </P>
