I don't care for a lot of what RK says, but his books are good for motivational purposes. He does bring up a lot of good ways of thinking that are against the conventional 'wisdom' (which usually isn't very wise).
He has always preached that your home is not an asset, which at the time was a far out concept, but looking back, it seems he was ahead of his time. It's interesting reading that makes you look beyond the 'rat race'.
I never thought of any of his books as instruction manuals on how to get rich, just that it is important to get out of the shrinking middle class. If the middle class was shrinking before, it just got thrown in the dryer on high heat, so this info is more important than ever.
I don't care if he had a 'rich dad' or if he made the whole thing up. Shoot the messenger if you want, but pick up the message from the floor and read it. Bottom line, his original book is good beginner reading for anyone who doesn't want to die broke. If you are hoping to retire from your 401k, you will die broke.
