Derivative Metaphore

I attended a derivatives workshop recently, and saw an overview of the latest and greatest in financial products. I came away with my eyes wide open... wide open with fear. Exotics. Hedging. Swaps. With this stuff going on, I'm amazed the financial crisis didn't come sooner and deeper. Basically you're gambling with borrowed money. On the outcome of the Super Bowl three years from now... and the World Series, and the Champions League.

I was brought up being taught that I can spend money only once. Apparently day traders don't think this way at all.
