From what I read, real returns are NEGATIVE as the investment choice is none, none but gov't bonds lol. I hope this was just a failed lead balloon test, I haven't seen much lately since it was announced nearly a year ago.
If the gov't wanted to help people save instead of having poor people finance the gov't in this creative way, they'd just give them enough of a "credit" with any of the banks or brokerage houses offering IRAs/Roths to get started and an incentive to keep going. The incentive already exists in the savers credit, and people CAN spend their tax returns on opening up a retirement account instead of buying a car or going on a vacation. I guess consumption is too important for the economy for the gov't to dissuade people from these dumb choices though...
