Why Buffett told his wife to put everything in index funds

On Wealth Demystified we break down one of the most famous pieces of investing advice ever given. In his will, Warren Buffett instructed the trustee to put 90% of his wife's inheritance into a low-cost S&P; 500 index fund. Why would the world's greatest stock picker tell his own family NOT to pick stocks? This video unpacks the logic behind that decision and connects it directly to JL Collins and The Simple Path to Wealth. Buffett understands that for almost everyone, low-cost index funds quietly outperform active management over time because fees and human error compound against you. We explain what an index fund actually is, why simplicity wins, and how you can apply Buffett's own advice starting today. If you are new to investing and want a strategy that is proven, boring, and effective, this is where your journey begins.
