Why do private insurers support Obamacare?

From: Reason

"As for the insurance companies, they worry—legitimately—that a government insurance company—the so-called public option—would drive them out of business. This isn't alarmism. It's economics. The public option would have no bottom line to worry about and therefore could engage in "predatory pricing" against the private insurers.

But despite these differences, the biggest companies in these two industries are on board with "reform."

It illustrates economist Steven Horwitz's First Law of Political Economy: "No one hates capitalism more than capitalists." In this case, big business wants to shape—and profit from—what inevitably will be an interventionist health-care reform. Can you think of the last time a major business supported a truly free market in anything?"
