"Rule #1 is “win at any cost. As long as they can commit fraud without suffering personal consequences, fraud will be the business model for Wall Street."
Unfortunately, even their consequences when applied has them still making out like bandits. They calculate this. When caught red handed and dead to rights... the "fine" of 20 Billion doesn't discourage them one bit when the "fraud" nets them 70 Billion. It's clearly just a business decision which is a win-win situation even when they lose. When they're fined, excuse the expression, they're laughing all the way to the BANK.
Sadly, "fraud" is the business model of many big businesses today. The business model that we have allowed to develop is psychopathic in nature, putting wealth over health, life, and the future of society and the planet. When a corporation's realization that their faulty product or a part of their product WILL cause deaths (limited life spans, destruction of the environment, etc) they will weigh out the cost of that loss of life up against the cost to redesign or even replace a $20 part to make it safe. If the cost is greater than the fines or law suits for loss of life...they believe they have a "fiduciary responsibility" to shareholders (and their BONUSES) to continue regardless of the disastrous consequences. With full knowledge that a mining or drilling process will cause the deaths of a hundred nearby innocent residents and contaminate the surrounding environment for decades or even centuries to come, a corporation will weigh the expenses of such a disaster up against what they may stand to gain in profits --- IF they get caught, and IF they can't pay the right politicians. This is insanity, yet it's what we allow to be called "business". Civilization is eventually doomed with this psychopathic business model.
