http://en.wikipedia.org/wiki/Tool_(insult) The word "tool" may be used as an insult, describing someone who is being manipulated without their knowledge, implying they are naïve and ignorant. The most common use is to describe someone who is being used by large corporations, the government or most commonly pop culture. In this context, the term is thought to be a contraction of "tool of the system". The insult is used in Western counter-culture to describe strong proponents of those institutions, who seem to truly believe in what is thought of as a mass deception.
The market's interest is different from mine. I want to make money, but the market prefers losers, because if there are to many winners there will not be enough losers to make the winners winners (hope you understand what i mean). So either way i will be fired. If i make profit the market will fire me, if i lose money i will have to fire myself.
