What these companies have done is come out against the proposed government run health care plan. This is the political class making its move to harass and intimidate private companies that oppose their view...this action IS illegal and a violation of their oath of office.
Plato showed the pitfalls of democracy (we are supposed to be a Constitutional Republic) in 'The Republic'. Democracy always degrades to tyranny:
"The excessive freedoms granted to the citizens of a democracy ultimately leads to a tyranny, the furthest regressed type of government. These freedoms divide the people into three socioeconomic classes: the dominating class, the capitalists and the commoners. Tensions between the dominating class and the capitalists causes the commoners to seek out protection of their democratic liberties. They invest all their power in their democratic demagogue, who, in turn, becomes corrupted by the power and becomes a tyrant with a small entourage of his supporters for protection and absolute control of his people."
