More privatization of healthcare equals higher costs

Paul Krugman says that "the power of competition" does not drive down healthcare costs:

For one thing, even if you buy the premise that competition would reduce health care costs, the idea that it could cut costs enough to make insurance affordable for Americans with a history of cancer or other major diseases is sheer fantasy.

Beyond that, there's no reason to believe in these alleged cost reductions. Insurance companies do try to hold down "medical losses" — the industry's term for what happens when an insurer actually ends up having to honor its promises by paying a client's medical bills. But they don't do this by promoting cost-effective medical care.

Instead, they hold down costs by only covering healthy people, screening out those who need coverage the most [...]. They also deny as many claims as possible, forcing doctors and hospitals to spend large sums fighting to get paid.

And the international evidence on health care costs is overwhelming: the United States has the most privatized system, with the most market competition — and it also has by far the highest health care costs in the world.
