Both a demand curve and a demand schedule show how

prices affect consumer demand.
consumer demand affects income.
prices affect complementary goods.
consumer demand affects substitute goods.

I believe the answer is: prices affect consumer demand.

Each consumers in the market have different level of income. As the price of a product increased, there would be less consumers that able to afford the product, which will lead to a decrease in the demand (the opposite thing happen if the price of the product decreased).

health care plans in the united states having high costs because they are focusing on providing quality programs for different groups of individuals. the quality of the service is based on money flow received from the members. without this investment, couldn't be possible a constant scientific searching to prevent death and illness caused because of low levels of health investigation. currently, the complaints are not about the highest cost, but about the coverage and benefits to access the necessary health services required by the members.  

besides, if a global health system is established the quality levels will fall down because of the standardized of the health. the access to care will increase but the quality will be low because it depends on the money invested.

ok whats to talk about were you scared or what?
