Medicare is the most popular and effective means of supplying health care to the most people. We should obviously extend the best and most effective method available to us. For those who claim that health is not a right should understand that life depends on health so if you consider life a right then everything life depends on should be taken care of. Either way, just saying health is not a right does not excuse the necessity of single payer. Consider reading which is also not a right, but necessary for living a better life.
