I. Dont. Care.
Maybe some government retirement agent can pick the index fund. They should feel free to knock themselves out geeking out over it. They'd probably just contract it out to Vanguard or whatever. Great and fine. I don't want to do it.
Our insistence on privatizing and individualizing everything just makes more busywork for everyone. I have an HDHP and HSA and it's frankly awful having to log in all the time and look for claims and pay the doctors from it and all that on top of the Explanation of Benefits form that comes from the insurance company and the separate bills from each doctor and me in the middle having to tell customer support from hospital X to talk to insurance provider Y over line item Z arrrrggggghhhhhhhh! I just want to go to the doctor!
Somehow voters keep optimizing for the geeks. Yes, there are a handful of people out there who enjoy spending their valuable time hunched over a spreadsheet looking at investment funds. They get their way with these hyper-individual 401(k) accounts. Screw the rest of us who just want to live their lives and then retire.
