Veteran investigative journalist Bethany McLean states that S&P 500 index funds are heavily skewed towards "hyperscale companies," making them a concentrated bet on the AI economy rather than offering broad market diversification. She also points out that the free cash flow of the Magnificent Seven is quietly turning negative, and circular financing within the AI ecosystem makes it difficult to see the true picture. Furthermore, McLean believes that the Federal Reserve's interventions over the past few decades have created moral hazard and tended to benefit large corporations and the wealthy, rather than small companies and ordinary consumers, while also fueling inflation.
