How do I draw a supply and demand curve for free health care where the amount of doctors are half the supply of the amount needed by a population? Doctors do not increase, so the supply curve is inelastic and is vertical at 100,000 doctors for example, yet the population has grown to 200,000 for example, yet the amount of doctors has stayed the same? I am not sure how to draw the population demand at 100,000 and then the new demand curve at 200,000.
