>Do we think index funds will continue to be this financial savior for regular people in the future? I've never argued that there are not market inefficiencies that can be exploited by active managers, but the twist is the very act of exploiting those opportunities quickly eliminates them. Thus why it's so hard for an active manager to beat index funds long term. If you're worried about a few high market cap companies dominating stock indexes, you could always tilt towards small cap value. That sector has under performed for decades, but every dog has it's day.
