The number of uninsured U.S. residents has grown to over 45 million (although this number includes illegal immigrants, etc.). Health care has become increasingly unaffordable for businesses and individuals. We can eliminate wasteful inefficiencies such as duplicate paper work, claim approval, insurance submission, etc. We can develop a centralized national database which makes diagnosis and treatment easier for doctors. Medical professionals can concentrate on healing the patient rather than on insurance procedures, malpractice liability, etc. Free medical services would encourage patients to practice preventive medicine and inquire about problems early when treatment will be light; currently, patients often avoid physicals and other preventive measures because of the costs. People will have an easier time starting their own business or working part-time if health insurance is covered. Patients with pre-existing conditions can still get health coverage.

There isn't a single government agency or division that runs efficiently; do we really want an organization that developed the U.S. Tax Code handling something as complex as health care? "Free" health care isn't really free since we must pay for it with taxes; expenses for health care would have to be paid for with higher taxes or spending cuts in other areas such as defense, education, etc. Profit motives, competition, and individual ingenuity have always led to greater cost control and effectiveness. Government-controlled health care would lead to a decrease in patient flexibility. The health-care industry likely will become infused with the same kind of corruption, back-room dealing, and special-interest-dominated sleaze that is already prevalent in other areas of government. Patients aren't likely to curb their drug costs and doctor visits if health care is free; thus, total costs will be several times what they are now. Just because Americans are uninsured doesn't mean they can't receive health care; nonprofits and government-run hospitals provide services to those who don't have insurance, and it is illegal to refuse emergency medical service because of a lack of insurance. Government-mandated procedures will likely reduce doctor flexibility and lead to poor patient care. Healthy people who take care of themselves will have to pay for the burden of those who smoke, are obese, etc. In an effort to cut costs, price & salary controls on drugs, medical equipment, and medical services are likely to be put in place, meaning there is less incentive to pursue medical-related research, development, and investment, nor pursue medical careers in general. A long, painful transition will have to take place involving lost insurance industry jobs, business closures, and new patient record creation. Loss of private practice options and possible reduced pay may dissuade many would-be doctors from pursuing the profession. Malpractice lawsuit costs, which are already sky-high, could further explode since universal care may expose the government to legal liability, and the possibility to sue someone with deep pockets usually invites more lawsuits. Government is more likely to pass additional restrictions or increase taxes on smoking, fast food, etc., leading to a further loss of personal freedoms. Patient confidentiality is likely to be compromised since centralized health information will likely be maintained by the government. Health care equipment, drugs, and services may end up being rationed by the government. In other words, politics, lifestyle of patients, and philosophical differences of those in power, could determine who gets what. Patients may be subjected to extremely long waits for treatment. Like social security, any government benefit eventually is taken as a "right" by the public, meaning that it's politically near impossible to remove or curtail it later on when costs get out of control.
