If these companies can't live under the regulations placed upon them by virtue of the corporate status, then they can always reorganize as some non-corporate entity.
That's true. But as long as they are under the jurisdiction of the United States, and as long as they sell stock in the United States to American Citizens, they have to abide by certain regulations. Corporations exist at the good pleasure of the sovereign power under which they are incorporated.
If CEO compensation packages are so important to a corporation that they are willing to disband their companies and move to a foreign country, then I don't want them here in the first place.
