Query: Extremely repetitive...

The book gives lots of interesting statistics about millionaires vs. non-millionaires at similar income levels, but basically repeats one concept paragraph after paragraph, page after page: People with high wealth have high income that they spend thriftily and invest well, while high wager earners with lower wealth than they should have spend outrageously on luxuries...what a surprise! For a chapter or two that might be an interesting theme, but this is almost the entirety of what the book has to say about "millionaires." There's a few useful tidbits about how these millionaires actually manage to be thrifty, but nothing too groundbreaking. A ten page version of this book could serve an identical function to its 300+ pages of rambling and statistics.
