I think the downvote is due a lack of understanding rather than disagreement. What is perhaps not obvious is that payments towards 'social security' in excess of the $106k cap is (or ought to be) allocated towards the payment of interest on those outstanding bonds, hence the apparent linear increase.

But also, your references to 'the truth' unintentionally gives you the air of a conspiracy theorist.

Incidentally, it's noting that the solvency projections are not inevitable but are based on the assumption of steady demographic change. It will be interesting to review these when the 2010 Census data becomes available in December or early 2011.
