BOSTON (TheStreet) -- How would you fix America's retirement system?Retirement USA a year ago asked that question in advance of a conference on "'Re-Envisioning Retirement Security" in seeking proposals for an alternate retirement system to replace what its membership says is a failed system of 401(k)s. A year later, in addition to what was used for that conference, 25 alternative retirement system plans have been submitted, revisited and revised. Two other proposals will be formally added to the roster in the coming days and other groups are also drafting their own re-imagining of retirement security, says Karen Ferguson, director of the Pension Rights Center (PRC), a non-profit consumer advocacy group. PRC is a member of Retirement USA along with the AFL-CIO, the Economic Policy Institute, the National Committee to Preserve Social Security and Medicare and the Service Employees International Union. Also developing proposals is the Society of Actuaries through its Retirement 20/20 initiative, which brings together companies and organizations with an interest in developing new retirement systems. At a June conference, six plan concepts were presented. This month, Retirement USA stepped up its advocacy efforts, particularly through "Wake Up Washington," a campaign intended to share personal stories of savings struggles with elected officials. "The common theme in all of this is that there is widespread anxiety among individuals," Ferguson says. "They are terrified. They all think it is their fault they don't have enough money and don't realize it is a structural problem. If they lived in most other industrialized countries, they wouldn't have this anxiety." Among the proposals being considered by Retirement USA, the most controversial, at least given the ire it has inspired among conservative pundits, is the Guaranteed Retirement Account Plan developed by professor Teresa Ghilarducci, director of the Schwartz Center for Economic Policy Analysis at the New School for Social Research. The proposal is often derided by conservatives and Tea Party supporters as an effort by the government to "seize your 401(k)." The very mention of Ghilarducci and her plan at a recent congressional hearing on retirement security was enough to rekindle the opposition and conspiracy theories. Conservative bloggers heaped scorn, once again, on the proposal as a "Ponzi scheme," a means to line politicians' pockets and perpetuate out-of-control spending and yet another "pitchfork moment." The GRA proposal mandates a contribution of 5% of earnings (up to the Social Security wage base) for all workers -- evenly divided between employer and employee. The employee's share of the contribution would be offset by a $600 refundable tax credit, which would cover the contribution obligation of an employee with income up to $24,000. The contributions of husbands and wives would be combined and divided equally between their individual accounts.
