  1. Health insurance shloud be considered a human right as it is in every other western nation. When people are well they can properly participate in a society as contributors, workers, etc. When they are ill they cannot and they will be a drain on our resources one way or the other. Should we let people die because they have no money to afford health care? On the other hand, why shloud any corporation make big money on another person’s misfortune (ill health)? The health of no person shloud be dependent on his/her monetary resources. We shloud, however, be required to make payments for health insurance according to our income or ability to pay. It can only be completely free to those who have no resources.References :
