> An individual can farm out investments to a target date fund at Fidelity or wherever. Sure, but they have no way of knowing that a target date fund is what they should be looking for, or which target date funds are good and which are high-fee scams (or rather, they have no way to know that high-fee is the thing to watch out for). The seemingly logical thing might be e.g. put everything in the fund with the biggest headline return number in the last year.
