question:
Person1: Can you believe the headlines ?
Person2:What are you reading ?
Person1: I ' m reading about Michael Milliken , the Bond King .
Person2:Didn ' t he sell worthless stocks to people or something ? He got arrested for that , didn ' t he ?
Person1: He got arrested all right .
Person2:If I remember , he got off with a light sentence . Something like three years in a minimum-security prison .
Person1: Yup , that ' s him . He made millions of dollars selling bonds to people and ended up with a pile of cash when they became useless .
Person2:I think the government fined him a small amount , and he kept the rest in his foreign bank accounts . He ' s still a millionaire .
Person1: That ' s the kind of thing in America that gets me mad . Some guy pulls off a stock scheme and makes millions while spending the bare minimum sentence in jail .
Person2:I know . And some poor guy that robs a liquor store makes $ 500 at most and ends up in jail for five to ten years .
