I think this is the kernel of what Bogle was saying and Vanguard is now reaping the benefits of.

Old system: active traders beat the market, therefore they charge fees slightly less than the alpha they're supposed to generate

New system: customers are more aware that their active trader(s) may not be the winners, so the acceptable fee to pay the traders decreases to the product of the alpha AND the risk of not picking the right traders
