Was it a perfect era? Was it really as "swell" as we see it in recreations? What were the hardships of the time?
No, not really. Unless you were a white, male, middle-upper class American citizen, it rather sucked. Ethnic minorities of every stripe were facing renewed attempts to stifle their rights. Women were forced out of the jobs and power they had gained during the War and everyone fell victim to the paranoia caused by the Cold War and threat of Nuclear destruction.
Beyond this all I can recommend is some reading, I can't point to the AskHistorians booklist enough, here is the general Cold War booklist and here is the US specific list. I'd also recommend African Americans against the Bomb by Intondi and Cold War Civil Rights by Dudziak.
