Smooth move.
As one of those people who used to have white hair (it has gradually returned to gray as I recover from ten years of caring for dying mother, father, and husband) I have serious disagreement with Christie on some of his Social Security thinking. Since he favors increasing Medicare premiums for well-to-do seniors, he should favor restoring the 90% wage cap on wages subject to SS withholding. This 90% figure was agreed to in 1983 by Pubs and Dems as a way to save SS. Unfortunately 1983 or 4 was the only time the 90% figure was used. The cap was set to inflation, but total wages earned was heavily influence by 10 to 20% increases in upper income earners salaries while the rest of us earned at the inflation rate or worse. The actual cap level has dipped as low as 82% since then. See Charts 4 and 5 and the explanation of higher wage imbalance between them as well as the Conclusion at: http://www.ssa.gov/policy/docs/policybriefs/pb2011-02.html
If we restored and kept the 90% bipartisan agreement, there would be NO SS CRISIS looming. If we increased it above 90% for a few years to make up for all the years it has been lower, the problem would be solved. People would not have to work past age 67 for full retirement or have their payments reduced. I wonder how many Wall St. bigshots who were earning $300 to $600 thousand before 2008, and now have trouble getting jobs paying more than $60 or $80 thousand, wish they had paid more into SS while they were flush.
