For some time the actuarial imbalance between revenues and benefit payments in the Social Security retirement programme in the United States has been a concern for decision makers, professional analysts, and the public. In response to this actuarial imbalance, President George W. Bush proposed in 2004 that changes be made in the method whereby Social Security benefits are determined and that individual investment accounts be established under the rubric of Social Security. The debate over the issue was intense, but it was effectively stilled by the middle of 2005. The probable legacy of the 2004‐05 debate is that limits have been placed upon future options to deal with the Social Security programme's financial difficulties. This article identifies those constraints which, together, constitute the new public policy “template” for future debates relating to the Social Security retirement programme in the United States.
