Howard: Say, answer me this one, will you? Why is gold worth some twenty bucks an ounce?
Flophouse Bum: I don't know. Because it's scarce.
Howard: A thousand men, say, go searchin' for gold. After six months, one of them's lucky: one out of a thousand. His find represents not only his own labor, but that of nine hundred and ninety-nine others to boot. That's six thousand months, five hundred years, scramblin' over a mountain, goin' hungry and thirsty. An ounce of gold, mister, is worth what it is because of the human labor that went into the findin' and the gettin' of it.
Flophouse Bum: I never thought of it just like that.
Howard: Well, there's no other explanation, mister. Gold itself ain't good for nothing except making jewelry with and gold teeth.
