BlackRock, Vanguard and State Street have over $15 trillion in combined global assets under management, an amount more than three-quarters of U.S. gross domestic product. Those assets are ultimately owned by their clients but they exercise shareholder votes without client input. You may think you're making a killing on your investments but they take away more with one hand than they give with the other. Finance, insurance, and real estate, the FIRE sector, siphons wealth and income upward to the richest 1% while impoverishing the middle class.
Not only are they too big to fail, competing businesses are really commonly owned by the same investors. They are the real central planners of the economy.
