Like most things American these days, it's all about money and easy ratings.
I liken the Occupy Wallstreet expressions to Watergate. The American public is tiring of a busted economy brought on by turned heads and lack of regulation on banks and investment firms.
It is sad when popularity directs the news. The days of Investigative Journalism that brought out the truth on Watergate took guts on the part of the Washington Post and its editor. To go against the current is hard, but needed.
