The United States government cannot afford to fund universal health care. Other universal social welfare policies such as Social Security and Medicare have run into major problems with funding. Costs are rising at the same time that the baby boomer generation are growing old and retiring. Soon tens of millions of boomers will stop contributing much tax and start demanding much more in benefits than before. In such a situation we cannot afford to burden the nation with another huge government spending program. Nations that provide universal health care coverage spend a substantial amount of their national wealth on the service.  With government control of all health care, caps will be placed on costs. As a result many doctors would not be rewarded for their long hours and important roles in our lives. The road to becoming a doctor is long and hard; without the present financial rewards many young people will not choose to study medicine. Current doctors may find that they do not want to continue their careers in a government-controlled market. The American Medical Association does not back a government-controlled, single-payer universal health care system.  The current system of offering group insurance through employers covers many Americans with good quality health insurance. The group plan concept enables insurance companies to insure people who are high risk and low risk by mixing them in the same pool. Issues over losing or leaving a job with health benefits are dealt with by federal laws which require companies to continue to offer workers cover for at least 18 months after they leave employment.
