Answer:
less
Step-by-step explanation:
In economics, all the present production or income is either consumed now, or a portion can be consumed now and and another portion saved for future consumption.
The implication is that when more is produced and less is consumed now, there will be more in terms of savings that can be consumed in the future. This is related to saving for the rainy day.
Therefor, In addition to producing more, Americans consumed less. They would use money saved during the war to spend on consumer goods after the war (which kept the economy from collapsing again afterwards).
