You say the issue is disclosure, but the question really is who is entitled to that disclosure. You seem to feel that the government is entitled to it. I vehemently disagree. If you were arguing that the investors in the hedge funds are entitled to it, then I might be more persuaded, but they entered into a contract with the hedge fund. That's the time they should be talking about disclosure, and they often are, so they don't need the government for that either.
Seriously ... go find another bogeyman.
When LTCM and BS failed, they required intervention by the Fed. Apparently, the current view is they have their privacy but we have the responsibility if they fail.
Sooner or later someone will hold a hearing on the Hill and information will begin to flow. Then there will be enabling legislation designed to make hedge funds more transparent. Again, there need not be actual regulation.
Finally, someone will work up the courage to wonder, for example, how much George Soros and others save on corporate and personal income taxes by locating their businesses off shore. Not only the taxes, but is it really possible with no reporting requirements for our financial system to avoid periodic failure engendered by hedge funds?
Take some guts. Both parties have been subsidized by big time hedge fund contributors.
I might not know much, but I know I need to know more but transparency is completely lacking.
