  "account": "On the 50th anniversary of Vanguard's launch of the first publicly available S&P 500 index mutual fund, index funds have grown to hold more than half of US fund assets. This financial innovation, often referred to as \"Bogle's Folly\" when it first began, has become a crucial tool for investors seeking to capitalize on US market growth at minimal cost.\n\nIn the early days, only about 5% of American households held mutual funds, but today, more than half do. The low cost structure of index funds has enabled almost 54% of all fund assets to be held in these funds, with $21.9 trillion compared to $18.8 trillion in actively managed funds.\n\nFounders like Jack Bogle and Eric Balchunas have credited the mutual ownership model of Vanguard for the success of index funds, as it led to reduced fees and a better value proposition for investors. Despite there being more than twice as many active funds as index funds, index funds are expected to consolidate in the coming years, with only a handful of companies controlling the majority of assets through low-cost, fee-efficient models.",
