As worker-directed pensions become the norm, American workers must inc
reasingly make complex investment decisions. In this Article, we argue
that the current system of pension regulation offers little protectio
n to the significant group of workers who are financially unsophistica
ted. The applicable fiduciary rules, found in ERISA, leave beneficiari
es unnecessarily exposed to unique risk by allowing trustees to make i
nvestments that are undiversified as long as those investments ate ind
ividually low in risk. We propose a two-part reform of the current rul
es governing pension fiduciaries. First, the basic standard governing
all fiduciaries should be revised to require fiduciaries to attempt to
eliminate unique risk. Second, small plan administrators need guidanc
e about investment strategy in the form of a system of safe harbor rul
es. Indeed, small plans should be encouraged to contract out the admin
istration of their funds. With adequate fiduciary rules, an expanded s
ystem of worker-directed plans might have many advantages over the cur
rent system of defined benefit plans, which have proven tremendously d
ifficult to regulate, and Social Security, whose unfunded benefit stru
cture reduces national savings and threatens the financial security of
the system.
