I find this almost comically revisionist.
400,000 US soldiers/marines never came home. Another 600,000 came back wounded. That's at least a million families affected.
And by 1950, only five years after the end of the war, millions of men were sent overseas again for the Korean War.
And after that, the children of the returned WWII soldiers were sent off to Vietnam, unleashing the greatest civil unrest in the US since the Civil War.
And you think it was a great time for all because the dollar was worth a lot?
