World War 2 question :)?

War always sees an increase in production. War is an expensive business, but also very important in invented technology. New inventions and new designers increase dramatically in times of prolonged war, driven by the necessary need to gain an advantage over the enemy. You also have the increase in industrialisation. Both WW1 and WW2 saw new and old factories converted to the armament industry, rolling out tanks, military equipment, rifles and ammo. Consequently more people are employed in the factories and therefore in other service industries. More soldiers mean more uniforms to be made. Increased activity by ships and military vehicles mean more oil and historically coal has to be produced and transported. This results in the need for more miners, transporters, and administrators.

War is expensive. But War can also drive your economy. In Russia in 1917, 70% of all factories in the industrial West of the country were related to the armament industry. One factory there had 20 000 workers everyday doing their jobs. (Putilov Iron works).

more than likely all the death incurred would though.
