What was the impact of World War 2 on US socially economically and politically and how did it change her relations with rest of the world?

People are not living life the way they are supposed to. They are struggling to get their next meal after the of the war. they will have to manage with wearing the same clothing every day, every night. They will also have to drink water that are polluted with deadly chemicals. The effected families will have to find a place to sleep next to their big pile of rubble, which used to be a well conditoned house. The parents would have no buisness or work to go to nad they will have no money and at the end of the day all the shops would have been demolished aswell.
