There have been few ideas by Congress more popular than 401(k) Plans.
In the 20 years since Congress invented the 401(k) Plan, over $1.7
trillion dollars have been deposited by employees. It is safe to say
that essentially 100% of the employees in companies that do not offer
401(k) plans put pressure on their employers to start a plan. Employers
pay the cost of starting and maintaining a plan and often provide matching
contributions as well. In these plans, the enrollment is over 90% on
average.
