One piece of culture (a song, movie, book) that I’ve encountered recently that has to do with money is watching the movie, Wolf of Wall Street.
A rhetorical analysis that could be involved is why and how money affects human emotions and actions. Jordan Belfort was a great example of how money changed him throughout the 3 and some hours of the movie. Examples of textual analysis is how he talks and treats others throughout the plot and it clearly changes.
