If America is ever to realize its goal of equal opportunity, every citizen must have access to two things: a good education and sound medical care. With these, every person can go as far as his ability and his energy will take him. A taxfinanced system of health care such as Medicaid goes far toward meeting our obligation to ensure adequate medical care for all.
