But the problem that plagues the health care system is not just a problem for the uninsured. Those who do have insurance have never had less security and stability than they do today. More and more Americans worry that if you move, lose your job, or change your job, you'll lose your health insurance too. More and more Americans pay their premiums only to discover that their insurance company has dropped their coverage when they get sick or won't pay the full cost of care. It happens every day.
