What were the positive aspects of life in America in the 1950s?
The major positive about this time in US history was that it was prosperous and, it seemed, stable. The US was clearly on top of the world and US society seemed relatively stable and happy.
This was a time when the US was booming after WWII. The rest of the world was economically crippled by the effects of the war. The US economy boomed as pent up demand for consumer goods (things that were completely unavailable during the war and unaffordable during the Depression) exploded. This meant that people were becoming more affluent than ever before, with things such as cars, TVs, refrigerators, and other things becoming much more common.
At the same time, this was a time when society seemed stable. There were no large protest movements going on yet and therefore not much of a feeling of social strife like we have even today. The society had finally had a chance to simply relax and be happy after the Depression and the war. These were the years when it seemed that US society was perfect (to some).
