Read the excerpt from the interview with E. Y. (Yip) Harburg.

The prevailing greeting at that time, on every block you passed, by some poor guy coming up, was: "Can you spare a dime?" Or: "Can you spare something for a cup of coffee?" . . . "Brother, Can You Spare a Dime?" finally hit on every block, on every street. I thought that could be a beautiful title. If I could only work it out by telling people, through the song, it isn't just a man asking for a dime.

This is the man who says: I built the railroads. I built that tower. I fought your wars. I was the kid with the drum. Why the hell should I be standing in line now? What happened to all this wealth I created?

Why does Harburg feel that "Brother, Can You Spare a Dime?" is a legitimate question, not just a plea from a beggar?
