Here is an article asking this important question ... one answer is bcuz people are sheep ...
Why Haven't Wall Streeters Gone to Jail ?
This article explains even more why they should obviously be prosecuted .... if we will prosecute a homeless man for stealing a pair of shoes ... these men have done way more damage ... Matt Taibbi is the best writer in America BTW ...
The People vs. Goldman Sachs
They weren't murderers or anything; they had merely stolen more money than most people can rationally conceive of, from their own customers, in a few blinks of an eye. But then they went one step further. They came to Washington, took an oath before Congress, and lied about it.
Thanks to an extraordinary investigative effort by a Senate subcommittee that unilaterally decided to take up the burden the criminal justice system has repeatedly refused to shoulder, we now know exactly what Goldman Sachs executives like Lloyd Blankfein and Daniel Sparks lied about. We know exactly how they and other top Goldman executives, including David Viniar and Thomas Montag, defrauded their clients. America has been waiting for a case to bring against Wall Street. Here it is, and the evidence has been gift-wrapped and left at the doorstep of federal prosecutors, evidence that doesn't leave much doubt: Goldman Sachs should stand trial.
Here is a story that provides hope that they may in fact be prosecuted .. but I doubt it ...
new investigation of the banks that apparently is being launched by New York State Attorney General Eric Schneiderman, which looks like it might be the first for-real attempt at a prosecution of the systemic corruption that led to the financial crisis.
Schneiderman’s probe, news of which came out yesterday in this piece by Morgenson, reportedly targets the banks’ mortgage securitization process during the bubble years. Morgenson reported that Schneiderman is focused on at least three companies: Morgan Stanley, Bank of America, and old friend Goldman, Sachs.
This investigation has the potential to be a Mother of All Nightmares situation for the banks for a couple of reasons. For one thing, the decision to go after the securitization process is a total prosecutorial bullseye. This is the ugly heart of the wide-scale fraud scheme of the bubble era. Again, the business model during this time was a giant bait-and-switch scam. Sleazy lenders like Countrywide and New Century first created huge masses of bad loans, committing every conceivable kind of fraud to get people into loans (from doctoring income statements with white-out to phonying FICO scores to engineering fake appraisals). They then moved the bad loans quickly to the big banks, which pooled them and chopped them up (this is the “securitization” process), sprinkled hocus-pocus math on them, and them sold them to suckers around the world as AAA-rated securities.
