This is what happens when you don't allow real competition into the picture. It's also what happens when you have a for-profit healthcare system:

Executives of three of the nation's largest health insurers told federal lawmakers in Washington on Tuesday that they would continue canceling medical coverage for some sick policyholders, despite withering criticism from Republican and Democratic members of Congress who decried the practice as unfair and abusive. The hearing on the controversial action known as rescission, which has left thousands of Americans burdened with costly medical bills despite paying insurance premiums, began a day after President Obama outlined his proposals for revamping the nation's healthcare system. An investigation by the House Subcommittee on Oversight and Investigations showed that health insurers WellPoint Inc., UnitedHealth Group and Assurant Inc. canceled the coverage of more than 20,000 people, allowing the companies to avoid paying more than $300 million in medical claims over a five-year period. It also found that policyholders with breast cancer, lymphoma and more than 1,000 other conditions were targeted for rescission and that employees were praised in performance reviews for terminating the policies of customers with expensive illnesses.

Isn't that lovely. Blue Cross is here for you!
