I am not saying that using or having a better position of data or information is wrong or illegal. I am saying that how they got there in the first place, and what they have done to ensure its perpetuity for them is what is illegal/wrong/exploitative and abused.
The worst criminals of the bunch are those in supposed positions of regulatory authority that are really there to protect the interests of big money.
This includes GS employees setup as Obama's economic advisory.
(Note: often people make the mistake of saying "well do you expect him not to hire/appoint people with intimate knowledge of how the financial system works?" -- No, I expect him to hire/appoint people with express knowledge of how the system works and how it is exploited and abused so that they can identify and go after criminal fraudulent activity.
When you hire/appoint those BENEFITING from the actions of the industry - it protects the criminal/exploitative activity!)
Because we force them to, through 401k's and the like.
My point is that there are a lot of things short of fraud that we consider "meritocracy" (and having superior information and superior analysis usually falls into that category), but those things systematically stack transactions in favor of the parties that can afford to buy them. Even if you have zero fraud, zero lobbying, etc, you'd still see wealth flowing to Wall Street from Main Street.
