Asking the impertinent questions

From the 1954 movie "Footsteps in the Fog," with Stewart Granger (wife killer!) and Jean Simmons (maid who is blackmailing him!). He offers to pay her off and send her to the USA.

Stewart: In America, for instance, there's no barrier of class distinction. With money, a girl like you could be a lady. 

Jean: What's the use of being a lady in a place where it makes no difference, sir?
