Justin,
I hear what you are saying, and agree that he advocates venturing into areas that are far riskier than most individuals are suited for. I agree that most people shouldn't follow his advice, and those who chose to should do considerable research outside the Rich Dad materials before beginning their ventures.
I agree that for most of us the passive investments, long term focus works best. However, take a look at the Forbes 400, and look for how many of them followed this method. Now, before everyone jumps on me, I know that none of us will ever be on that list (pretty certain of this), and we need to do things in a way that works for us, not chasing some pie in the sky. Just a reminder that it's not the only way to do things.
I know a young lady who, despite many people urging, had resisted beginning a career in modeling. After reading Rich Dad, realized that it could be a very good "side business" and pursued it. She has since incorporated her modeling career and makes a good (not supermodel like) living out of it, in addition to her day job. They don't all need to be high start up cost ventures.
I too liked his classification of assets and liabilities, which is why his latest article on Yahoo Finance surprised me. I stopped reading after this line, "Prior to 1971, the U.S. dollar was real money linked to gold and silver, which is why the U.S. dollar was known as a silver certificate. After 1971, the U.S. dollar became a Federal Reserve Note -- an IOU from the U.S. government. Instead of our dollar being an asset, it was turned into a liability."
The piece of paper that we call dollars was always an asset to the holder and a liability to the US Govt. The only difference is that it used to be a secured asset, now it is unsecured.
