Excerpt: There is abundant academic and empirical evidence suggesting the shift to consumer driven retirement will not optimize consumer well being due to behavioral impediments and generally low investment interest and acumen. This issue is well recognized and has been partially addressed by regulators and the retirement industry via 'fiduciary immunization' for automated contributions and prepackaged lifecycle driven investment products. 401(k) plan auto-enrollment and utilization of target retirement funds can overcome some level of investor inertia with regard to savings and investment decisions. However, these tools are limited in their ability to ensure retirement sufficiency across a wide range of investor circumstances and preferences.
