I don't even understand the argument you've made. From your original comment, it appears that you dove into a site full of graphs, came up with "405 billion shortfall", and declared the program imperiled. I can't find that number on the site (I may have spent less time looking than you did) and it doesn't square with the Trustees report or, for that matter, with the conventional wisdom that Social Security is probably not our big problem --- relatively small, long-overdue fixes to SSDI will more or less resolve budget concerns there --- but instead Medicare.

Your comment at the top of this thread is sort of a perfect illustration of the problems of sites like these.
