Pretty sure the recent precedent, as it regards to testifying before the Senate, is that perjury is not a crime. 
GS pays lawyers an astronomical amount of money to make sure everything unethical and immoral they do is completely legal and disclosed to the bare minimum allowed under securities laws.
If you liked that story, you should check out "The Big Short" by Michael Lewis. Good short read.
This is what is implemented by large corporations like GS under the guise of asking for deregulation. Really, they want their respective industries rigged so as to benefit them best. It is a re-regulation.
Technically, GS is not a corporation. But, you are right. The more regulation, the more opportunities to craft (i.e. lobby) the rules in your favor, while simultaneously making it more difficult for new market entrants (i.e. competition) due to regulatory entrance costs and ongoing compliance.
Deregulation is a misnomer when used in this manner you describe. However, true deregulation has proven lucrative to all americans, particularly small business owners (startups).
