On the surface it sells a false promise
Below the surface it's telling you "just be a rentseeker. Look down upon those who work for a living."
Like literally one of the grossest themes is the condescending tone of the rich dad towards workers like the poor dad. He literally considers being a teacher a wasted life because he's so blinded by greed and pursuit of money (which is freedom and power).
It's a gross hyper capitalist outlook on the world.
The only things of "educational value" in it are his discussion on assets vs liabilities which, considering likely everyone here lives under capitalism, is worth knowing and understanding, although you absolutely don't need this book to learn that stuff.
The rest is a mixture of hopium, lies, disgusting myths about capitalism and other shit.
