I don't see what is so special about that book. It is really repetitious and doesn't really offer a lot of insight into much of anything.
The book was far from perfect. I won't nit pick it's many questionable formulas, etc.
But in general, it was SPOT ON, and in contradiction of what almost every American thought the "rich" were like.
It helped dispel the notion that most millionaires were like the glittering rich you'd see on "Lifestyles of the Rich and Famous"- ostentatious, self absorbed movies stars, athletes, and CEOs who bathed in Crystal in hot tub in the back of their Bentley while screwing 20 $1,000 per hour hookers at the same time.
Most millionaires and multimillionaires are NOT "Donald Trump" or similar "hey, look at me!" a-holes, but just regular folks.
As a true millionaire next door type (well, I wasn't quite a millionaire when the book came out, but well on my way), I always wondered if there were more folks like me who lived like the middle class, but had significantly more assets.
Now, I'm the multi-millionaire next door. I still live in the same (middle to slightly upper middle class) neighborhood I lived in back in '97. I still live the same lifestyle I did when I was a $100,000'aire. Hell, I really don't live a whole lot higher than the lower middle class lifestyle I grew up in- there are a few exceptions- the larger house, my wife's Beemer, but I still mostly live like my parents.
TMND flew in the face of "conventional wisdom." It helped me realize that I was not alone, that there are people like myself all around.
A very flawed book in many ways, but at the same time, a revolutionary work.
