SOX was 2003 - and after it was implemented a bunch of folks nearly took down the world economy all while saying they complied with both SOX and the "highest ethical standards".
The folks who wanted to take down the country faced almost NO consequence and SOX did little to prevent it. Seriously - thousands of companies jump through regulatory hoops - and the aggressive players get off with nothing.
There are lots of people (most people) working to do the RIGHT thing. It's SUPER annoying to have people put in huge efforts to get a bunch of small things right, and then to have goverment totally fail to enforce truly 101 big things.
I would trade out some of the stuff that 4,000 companies and 100,000's of individual have to jump through for even 100 companies getting some actual enforcement action. Everything from IRS audit to anything else you can think of, just at least make there be some consequence for the 101 style abuse of the systems.
Even auditing another 10,000 individuals, 200 additional executives - the number of folks putting money offshore - with full disclosure now available through leaked documents and information sharing, there should be 1000's of cases to chase this stuff down, not just voluntary disclosure programs.
