greater mobility across the nation
how sure are you
I am pretty confident in my response, as greater mobility across the nation during the 1920s played a significant role in the rise of mass culture. This allowed for the spread of ideas, trends, and entertainment across different regions, contributing to the development of a more unified national popular culture.
