Sounds like a self correcting problem easily solved by a little profit motive. As index funds gain ownership, the cost for an active investor to buy enough stock to vote whoever they want into control of companies decreases as the number of active voters decreases. Once that gets low enough and the CEO is deemed running a company badly enough, some active investor will buy enough stock to vote in better management and if successful, will rake in a healthy profit for doing so as it'll result in excess returns.
