Some foundational barriers seem to exist in the hopes of exending health care to as many people as possible. The most relevant one is cost. As an industry, health care's cost are profound. Some of these costs are genuine, in terms of procedure, research, and basic care, while others could be the results of a system that has been unregulated for so long that some aspect of inertia and "bloated" realities account for high costs. This automatically leads to exclusion of those who are on the lower socio- economic level of a social order. Additionally, in many nations, insurance providers quantify coverage based on health conditions. This means that if an individual poses a health risk, their cost of insurance will reflect such a state. Individuals who have not been able to afford the benefits of health care might be suffering from poor health, making their coverage more expensive, precluding coverage and application of basic health care as hospitals can choose to deny care to individuals who lack insurance. Additionally, in many nations the best and most applicable elements of health care exists in the urban setting or cities. Individuals who live in the rural areas cannot experience this unless they travel to the city, which, in some cases, is infeasible. Advances in health care and the greater level of intricacy exist in the city setting, and do not often trickle down to the rural one.
