Follow the money.

OK, this business of Barclays Bank falsifying the Libor rate (the rate at which banks lend money to one another) so that their traders can make extra money betting on it - very naughty and almost certainly illegal, but what I can't get my head round is - who are the victims?  Just who is being defrauded?  And as far as I can see, it's other traders.  It's a zero-sum game.  What one trader wins, another loses.  Still naughty and probably illegal, but if one dodgy trader takes money off another dodgy trader, should we be bothered?  What I think we should be looking at is the bonuses which these traders get.  If as a result of winning more money gambling on the Libor rate a trader gets a bigger bonus than he otherwise would have, that bonus is effectively paid by the shareholders - which may very well include us, taxpayers.  Now that is definitely a matter for concern.
