Technically speaking, a 401(k) is a type of pension

The prevalence of 401(k) plans and IRAs over pensions shifted investment risk from employers to employees.

The 401(k) is limited in its ability to provide guaranteed retirement income

Part of the problem is the high, often hidden fees associated with the accounts and a lack of access. Plus, analysts say the annual cost in tax revenue to the government is more than $100B.

Ted Benna is the father of the 401(k)

401(k) plans and pensions differ in who has control over the investments

With pension plans, a company contributes to an investment fund from which it distributes regular payments to a retired worker until their death. A 401(k) gives the worker control over contributions in a tax-advantaged account.

Researchers, experts, and retirees are finding that the 401(k) has left much to be desired

Roth 401(k) plans vs regular 401(k) plans
