Yep, I've actually already applied to all three of those places. Vanguard would be my first choice of the three because I could do more outside of focusing strictly on investments, and actually have an advisor type relationship with people. You're right though in that I do have hesitations about being in this industry at all, because:

• I am too anti-fee (e.g. why pay a fee on an IRA account at Wealthfront/Betterment? Yes, it’s better than what most people would do on their own, but it’s still not the optimal… I go back and forth on this one, because I do put a high value on the simplicity of it).
• The business is based on meeting with lots of people and selling to them, and the people I would get along with the best are probably doing this stuff themselves
• There’s tension between what this would be focused on (manage money effectively, accumulate wealth) vs. my desire to be more EA and act on the knowledge that I have enough, and many others do not.

I haven’t heard back from any of the applications, so it’s a moot point right now.
