Just some ideas off the top of my head of what I think of when I consider that time period.
After the war a number of things started happening in the US and continued through the 1950s.
-The US had already become more industrial and urban (suburban). Before the war the US was still largely agricultural except in the industrial areas (what is sometimes called the Rust Belt now). Now people wanted jobs in factories and offices all across the country. This was were the "good jobs" were.
-Many returning soldiers now wanted to do more than stay "down on the farm". They had a chance to go to college with the GI bill. They had big dreams for a bright future.
-More highways were built. More people bought cars. A move to the suburbs began. The "American dream" in many locations became a 3 bedroom/2 bathroom home on a shady suburban lot.
-Women in the workplace was changing. After the war many women who had been employed in factories or the war effort went back to being housekeepers, but many (most?) of the younger women now wanted a job outside of the home even if they were married. I'm not sure of the percentage, but many women before the war had never learned to drive. Two-income family became more common.
-Manufacturers turned to consumer goods; cars, refrigerators, washing machine and all the other "labor saving devices" as well as television.
-Many thought atomic energy was the wave of the future. It was once said that energy would be "too cheap to meter."
-Downtowns were starting to change as malls and shopping centers were built in the suburbs.
-Racial divides were starting to break down (in the army, baseball, schools, etc.).
-Because more people had dependable cars and there were more highways, people took more vacations by car. Motels and "motor courts" spring up all over the country.
-The early version of fast food or national chain restaurants started to appear.
-Shopping changed. It used to be that grocery stores were like the one in the Andy Griffith Show; locally owned and run by mom and pop, or small regional chains. Now national supermarkets began to dominate.
-Flying for either business or travel became more common.
-People moved more, and further. Someone might pick up their family and move to California from Kansas, for example.
And we were all going to soon have flying cars and colonies on the moon and under the oceans.
