Robert Kiyosaki, author of 'Rich Dad Poor Dad,' has criticized the traditional 60/40 investment portfolio, arguing it became outdated in 1971 when the U.S. dollar left the gold standard. He labeled the U.S. government as the 'largest debtor in history' and questioned the value of U.S. bonds. Kiyosaki endorsed Morgan Stanley's 60/20/20 portfolio strategy, which allocates 60% to stocks, 20% to bonds, and 20% to gold, for long-term financial security. He highlighted gold's superior performance over stocks and bonds and expressed a preference for real assets like gold, silver, Bitcoin, Ethereum, rental income, and oil, claiming these have contributed to his financial freedom for over 30 years.
