I expect that a 2060 Target Date Fund is aimed at the parents of teenagers and not the teenagers themselves.  It's probably playing on the (legitimate?) concerns that returns will likely be lower over the next several decades and that your kids will live longer.  Compounding makes a huge difference but teenagers won't have the financial wherewithal, sophistication or compunction to start thinking about retirement until they are stuck in a hopeless game of catch-up.   So why not give them a headstart? i.e. "you won't even notice the $1,000 (or whatever amount) a year you put in the fund, but it will make all the difference down the road for your kid".   Personally, I find that argument kind of compelling.  I invest my son's Canada Child Benefit in an informal trust in his name.  It's only a small amount each year but I treat the money like it was never mine to begin with.  

Alternatively, this fund is targeting the wealthy, such as parents looking to set up a trust fund.
