I disagree.. the most important message in the book is that business and entrepreneurship is the path to success, NOT being an employee and staying in the rat race. While it may be common sense to someone who's been in business for a while, or read a lot of similar literature, it's far from obvious to most people. I'm not ashamed to say Rich Dad Poor Dad has been one of the most influential books I've read in my life…
The best book that I have read that emphasizes this point is "The Millionaire Fastlane" — awesome, awesome read ... a must for anyone starting, running, or thinking about creating a business.
