Health care costs

Many forms of social insurance systems control their costs by using the bargaining power of the community they are intended to serve to control costs in the health care delivery system. They may attempt to do so by, for example, negotiating drug prices directly with pharmaceutical companies, negotiating standard fees with the medical profession, or reducing unnecessary health care costs. Social systems sometimes feature contributions related to earnings as part of a system to deliver universal health care, which may or may not also involve the use of commercial and non-commercial insurers. Essentially the wealthier users pay proportionately more into the system to cover the needs of the poorer users who therefore contribute proportionately less. There are usually caps on the contributions of the wealthy and minimum payments that must be made by the insured (often in the form of a minimum contribution, similar to a deductible in commercial insurance models).
