Kiyosaki is one of the worst scammers of all time. His books are not only wrong but dangerous to your financial health. Absolutely irresponsible. He got rich by writing books about how to get rich. This is a must read:
Read this some years back during the "Rich Dad Poor Dad" craze. It opened my eyes I can tell you that.
Looks like it was written by someone attempting to promote their own book.
I actually got something useful out of the "rich dad, poor dad" book. I don't care if it is made up or not, but I like his encounter with the aspiring young author who thinks she is so much more worthy as a writer than he is. He then explains to her that he is known as "best selling author", not "best writing author". His books teach a good lesson about marketing, just think how much money he made just by choosing a catchy title.
The other thing where I think he is right is that you have to start trying things to gain experience. I know it sounds trivial, but it isn't (I don't think many people would think about investing in that way, anyway).
I do not deny that the book sells well, all I'm saying is that for the serious (aspiring) entrepreneur, it's not worth the money or the time.
