Vanguard is owned by their funds, so incentives are aligned with the shareholders of the funds. They are very different than most fund companies.
Vanguard actively moves clients from their baseline funds to the lower cost/higher minimum Admiral versions.
I just don't see moral hazard in Vanguard, compared to other financial firms with remotely similar capabilities and offerings.
The expense ratio of Admiral Index 500 is .05%, not .2%. So even better than I'd remembered.
