Argument: Universal health care would lower pay so reduce quality of physicians
"Should the Government Provide Free Universal Health Care for All Americans?" Balanced Politics.org - "Loss of private practice options and possible reduced pay may dissuade many would-be doctors from pursuing the profession. Government jobs currently have statute-mandated salaries and civil service tests required for getting hired. There isn't a lot of flexibility built in to reward the best performing workers. Imagine how this would limit the options of medical professionals. Doctors who attract scores of patients and do the best work would likely be paid the same as those that perform poorly and drive patients away. The private practice options and flexibility of specialties is one of things that attracts students to the profession. If you take that away, you may discourage would-be students from putting themselves through the torture of medical school and residency."
