What was the concept of "normalcy" based on?

pride in winning the war - Im thinking this

nostalgia for an earlier America

America's expanding role in world affairs

getting Britain and France to repay war loans

The concept of "normalcy" was based on nostalgia for an earlier America. The idea of nostalgia was new in Americans and since America was a new country, the forefathers wanted progress and did not want to look back in the past mentality.
