Sen. Bernie Sanders, I-Vermont, is famous for his advocacy of a single-payer health care, such as prevails in Canada. However, one feature of such systems is the long wait times that patients have to endure before they get medical care. A case in point exists in the United States, with the Veteransâ Affairs Department health care system, government run, that has featured secret waiting lists upon which veterans have all too often died while in line for vital health care services.
