President Barack Obama has undertaken the expansion of health care to the roughly 45 million Americans who do not currently have health insurance. Having about one American in seven with no health insurance is undeniably an undesirable situation which deserves our attention and concern.

This is not just a matter of compassion either, but also of practicality. About the most expensive way imaginable to deal with routine illness is to provide it in hospital emergency rooms, yet this is the only alternative for millions of people. In addition, the uninsured commonly defer getting needed treatment, and with the looming threat of infectious diseases to all our families, we are all at risk when millions go without needed treatment.
