Sadly there isn't much wisdom left in the world (duh, look around you). How people routinely sit and watch themselves get shafted, is almost (almost) comical in the demonstration of HOW lacking in wisdom most people TRULY ARE.
Even the (supposedly) "wise" people, turn out to be mostly halfwitted and naive to the gills. Wake up - no one cares - no one is honest in business - don't be gullible. ALWAYS assume people are out to shaft you, and try to not be too cynical whilst you're thinking that, but USE YOUR BRAINS and INSTINCTS (that is why GOD gave you them!)
Money ALWAYS seems to override instinct and gut feelings - I don't understand why people are bought and sold SO EASILY; ignore the figures, FOLLOW YOUR GUT FEELING, and if you are sensitive to that, and smell a rat, EVEN IF THEY OFFER YOU £500M, tell them politely - "seeya, no thanks". Walk away, say nothing - NOTHING.
