WWI really changed the way youth saw the world and themselves. While their parents may have lived in the same house their whole lives and never left their home states, these men and women saw foreign countries, met people from different backgrounds, and became jaded by the horrors of war. Subsequently, returning soldiers and nurses were too restless to stay and fulfill the life that had previously been destined for them. Many flocked to big cities or tried their hand at new careers.
How Ya Gonna Keep Em Down on the Farm (After They've Seen Paree)? perfectly illustrates this phenomenon.
