Your view is not congruent with mine. Banking staff just increase their annual bonus following the sophisticated application of the Banks way of doing business - Basically take sweets from babies, steal, kill and burn to death anything in the way of increasing the takings and ones own three times annual salary bonus.
So no, its pointless trying to send people to jail for following the rules of the game.
The problem is that the regulators are basically working for the banks, as are academics, as are media commentators. So no surprise that they all got together and shafted main-street.
Sending Bankers to Jail is pointless until the regulators actually regulate instead of taking home bribes.
The fact that the bankers knew they were screwing, and indeed still are screwing the rest of us we will leave for their consciences to deal with.
The real blame lies with the Politicians who would rather surf the wave of the boom whilst they are in power rather than take any long term action to prevent the inevitable crash. After all boom and bust is good for the economy, its just a bit hard on all the people it fucks. Lets hope that this incompetent handling of the economy doesn't ever fuck you, as you seem quite happy for it to continue. After all you believe that the free market will be perfectly fair and will operate just like the theoretical model of a free market that seems intellectually fair and optimally successful. There is no such thing as a free market, its either run by the government regulator, the mafia, a powerful entity overseas or the local criminal who has invented their own tax on you.
