Even if it doesn't drop off, you can make money by investing into businesses who give you better long-term growth and (related) dividends than the one that everyone else is buying through index funds which you know isn't doing well. This would require a long-term view similar to how Berkshire Hathaway is acquiring businesses. If active investors' short-term price speculation were reduced in favor of long-term bets, that might be a good thing for businesses and the economy overall. And of course, if this situation actually becomes commonplace, chances are the market for index funds is going to self-correct since a well-performing stock needs either solid dividends or above-average growth. A market with 100% indexing can not give you above-average growth, and dividends depend on actual business performance.
