was expected to contribute in some way; this served the double purpose of improving morale as well as resource conservation. A war effort was also used to help companies grow. An example of this was when the military would contract companies such as Boeing to produce war resources for them. That would eventually give room for innovation and technological advances for such companies. Closely related is the concept of the home front—i.e., that civilians engaged in wartime pursuits (particularly, industrial production) are in effect also fighting the enemy on a "front" of their own, and that the result of their "fighting" (higher productivity, refraining from labor disputes, strikes etc.) might determine the difference between victory and defeat.
