Why would the us and other countries need to ration or limit the amount of consumer goods available?

For war purposes or a massive famine

Explanation:

When countries go into war they might not be able to get food rations from other places, if a place cant get food they would ration it out towards the people. If there was a massive drought it would mess up farming and it would cause a famine.
