The testimony to the Senate is a wonderful insight into what is going on, and, the Fed and Greenspans’ thoughts on many issues. I highly encourage you to read the transcript. Both sides of the Senate spin the Chairman’s comments toward their own point of view.
So, go to the source, don’t use others’ interpretations, review all sides, etc. For example, read what Greenspan actually said, not what CNN thinks you should hear about what he said. Read the actual economic reports, not an interpretation of them by a pundit on a Sunday morning talk show. TV and Radio make money by being entertaining. This is the point of “my take” on current events. Read between the lines, think for yourself.
