Greenspan and the Fed cannot keep people from making stupid investments.

If you can find a radio station that carries Jim Cramer's RealMoney show, you might find many of his observations about the Wall Street prognosticators quite hilarious. (There's a web page at [link|http://www.thestreet.com/radio/|[link|http://www.thestreet.com/radio/|http://www.thestreet.com/radio/]], but it's more fun to listen than to read.)

One of the points he has made recently is that Wall Street *still* hasn't really learned to cope with the technology and changing investment climate that has surfaced over the past ten years or so. Market goes down 200 points, prognosticators blather about unemployment figures (or the latest "news", whether from government statistics or world news or whatevever) when they really don't know what happened or why.
