WHAT DO PRIVATE INSURANCE COMPANIES HAVE TO FEAR?

I wholeheartedly agree with President Obama on this statement:  "Why would [a government plan] drive private insurance out of business? If private insurers say that the marketplace provides the best quality health care; if they tell us that they're offering a good deal, then why is it that the government, which they say can't run anything, suddenly is going to drive them out of business? That's not logical." --President Barack Obama

If private insurance companies think they are doing such a wonderful job (denying claims, raising premiums and lowering benefits, refusing insurance because of "preexisting conditions," etc.), what do they have to fear from the government offering people a health plan that will actually cover them when they are sick, will keep premiums at a level people can afford, and never refuse insurance because of preexisting conditions?  Hmmm....I wonder....
