In America, millions make you middle-class

The book is not alone among new titles in offering clues on how to get rich. Among others are Robert Shemin's "How Come THAT Idiot's Rich And I'm Not" ($25, Crown) and Douglas Andrew's "Millionaire by Thirty: The Quickest Path to Early Financial Independence," to be published in May by Business Plus.

But one thing seems certain -- a million dollars ain't what it used to be. Prince and Schiff reveal that, on average, people believe it takes $13.4 million to feel wealthy. Middle-class millionaires put the figure even higher, at about $24 million.
