I used to have a great article explaining Social Security and how it wasn't in trouble - but that was hosted on a friend's web page which is no longer available. The short version was that folks use the most pessimistic analysis results - which have always been wrong - to "show" that Social Security is having problems.
This is a nice explanation with the politics thrown in. I suspect the issue really is this simple.
Hat tip to Quentin, with other similar videos.
