What is the meaning of the song lyrics of brother can you spare a dime by Rudy Vallee, 1932?

When this song was recorded in 1932, one out of every four Americans who wanted work could not find work. The banking system was near collapse. Record sales had plummeted because Americans did not have the money for such luxuries. No song captures the dark spirit of the Great Depression more than "Brother, Can You Spare a Dime?" The song was written for a Broadway musical, "New Americana." Rudy Vallee recorded the song shortly before President Roosevelt's election.
