Because they like the government to control the economy

The specter of fear is everywhere, not just on Wall Street. And the scale of the government’s reaction is no less than what it was after 9/11—that is what probably scares ordinary people the most. Yet no one who believes that the government exploited fears after 9/11 to strengthen its security powers is now saying that the government is exploiting financial crisis fears in order to justify taking control of credit markets. No one who thinks that government would use fear to curtail civil liberties seems to think that government would use fear to curtail economic liberties. Why not?
