New savings vehicles in the works?

Investment News suggested the following is being considered:

House Education and Labor Committee Chairman George Miller, D-Calif., and Rep. Jim McDermott, D-Wash., chairman of the House Ways and Means Committee’s Subcommittee on Income Security and Family Support, are looking at redirecting those tax breaks to a new system of guaranteed retirement accounts to which all workers would be obliged to contribute.

A plan by Teresa Ghilarducci, professor of economic-policy analysis at The New School for Social Research in New York, contains elements that are being considered. She testified last week before Mr. Miller’s Education and Labor Committee on her proposal.

George Miller: Looking at redirecting tax breaks to a new system of guaranteed retirement accounts.
At that hearing, the director of the Congressional Budget Office, Peter Orszag, testified that some $2 trillion in retirement savings has been lost over the past 15 months.
Under Ms. Ghilarducci’s plan, all workers would receive a $600 annual inflation-adjusted subsidy from the U.S. government but would be required to invest 5% of their pay into a guaranteed retirement account administered by the Social Security Administration. The money in turn would be invested in special government bonds that would pay 3% a year, adjusted for inflation.

The current system of providing tax breaks on 401(k) contributions and earnings would be eliminated.

I have not read anything from the Obama camp about such an idea, nor that “senior” Dems are even considering it. Thoughts?
