A bipartisan group of former legislators, academics, former state and federal government employees and business owners joined forces over the past two years to come up with solutions to America's retirement security problem.

The Bipartisan Policy Center launched the Commission on Retirement Security and Personal Savings in 2014.

"They really tried to look at it from a comprehensive standpoint," says Shai Akabas, associate director of economic policy for the Bipartisan Policy Center.

The commission looked at 401(k)s, personal savings, pensions and Social Security.

"They really thought that looking at the complete picture of retirement savings and income is what is necessary to come up with solutions that work well together and can substantially improve people's retirement outcomes," says Akabas.
