Yeah, but it&#x27;s totally rational, if you look at it another way.  The potential upside is that I make $250 M or $2 B dollars and reap some kind of bonus, right?  And the downside is that I lose my job and somebody ELSE loses the $250 M.<p>If you don&#x27;t care about anything other than yourself, why <i>wouldn&#x27;t</i> you make that bet?<p>I don&#x27;t think a lot of the traders are purposely thinking this, but the incentives are set up so that people who act this way are rewarded and start to dominate the decision making process.
