A trader gets to the meat of the matter about the market. I don't necessarily believe him when he says Goldman Sachs (and its ilk, I imagine he is implying) rules the world. Governments do have more tools at their disposal than Goldman Sachs. I don't necessarily think that there will be a huge global crash... maybe there will, maybe there won't. What I do want to pick up on is a comment that may have been lost in the hyperbole: "I'm a trader."
That one line is important. He, and the other traders, do not care about bailouts or stimulus packages. He's there to make money from the market. If the market goes south, he and his colleagues will find a way to derive money from it, which will magnify the crash. It's his job. It's the market as force of nature: the traders are simply filling their part of the ecosystem. This is what the market does. All he can say is "be prepared".
So, be prepared!
