Discussion of universal healthcare is nothing new for US politicians or among reform advocates, policy experts, or the general public. Physicians, however, have been minor voices in the discussion. Their relative silence has been detrimental both to the public and to physicians themselves. We pose 3 arguments as to why physicians should support universal access grounded in medicine's own self-interest, arguments that are largely ignored in the current debate. These are: (1) the need for paying patients, (2) the need for a sense of self-esteem rooted in professionalism rather than commercialism, and (3) the urgency to affirm a public purpose for medicine by promoting the nation's health through universal care. Who has a stake in universal healthcare? Some groups, such as those lacking insurance, are obviously at risk and have a keen interest. Others, such as insured workers, have a less obvious but demonstrable concern. Arguments that urge adoption of an inclusive system typically focus on "healthcare horror stories" designed to evoke sympathy for the unfortunate persons whose lives are forever changed by unmet health needs or unpaid health bills. Our focus is different. We ask, regarding universal healthcare, "What's in it for physicians?" While the active support of doctors may not be a sufficient force to change the US system, it is probably a necessary one. At a minimum, universal coverage will be far less likely if physicians are opposed to it. Our aim here is to explore and discuss some of the reasons that should motivate active physician involvement in a more just and equitable system. We will discuss 3 reasons in particular. They are: (1) the need for paying patients; (2) the need to take pride in what one does--that is, the need to be nurtured by recognition of skillful professional performance in medical work, and not just rewarded monetarily; and (3) the importance of embracing a public purpose for medicine and thus engaging the trust and esteem of the population. We will examine each of these in turn, but first we will discuss briefly the other constituencies for universal coverage, since their reasons for supporting an inclusive system are often shared by doctors.
