Here is an interesting scenario...
So, corporations and organizations can sue individuals. The burden of proof in a civil trial is one of preponderance of evidence in that on the evidence and testimony provided, the burden of proof required is one that "a reasonable person could believe that" X circumstance caused by Y party caused Z outcome which negatively affected the plaintiff, than the ruling is in the plaintiff's favor, as opposed to a criminal "beyond a reasonable doubt" burden of proof.
This being what it is, should/can the The President/The US Government, on behalf of the people of the United States, sue corporate executives and hedge fund managers who are directly and obviously responsible for the current economic crisis for placing the people/government into undue debt as well as false advertising...whatever.
If so, would that not mean that the mortgage holders who took the sub-prime and interest only mortgages be exposed to lawsuit on behalf of the people who did not take these deals, for creating the economic circumstances which contributed to the negative financial circumstances the "responsible" individual must now deal with?
The answer to question one is no, Reagan helped create corporate liability shields which would prevent such things. The answer to question two could be yes. Go see a lawyer...
