Probably make more sense to compute present value in terms of a future governed more by DEFLATION than INFLATION ~ much like today
The point at which non-interest income fell below program costs was 2010. Program costs are projected to exceed non-interest income throughout the remainder of the 75-year period. (April 2011).
In April 2011 they project fund exhaustion a year earlier than before. In May 2012 they project fund exhaustion 3 years earlier than the 2011 projection
In 2011 they're earning 4.6 percent interestand in 2012 4.4 percent (not sure how this works, given that SS payments are then "loaned" to the general fund), and one wonders what their interest rate projections are going forward.
I mean it's a shell game anyway, but point is I have trouble believing any government projections.
