The Law of Necessity
The law of necessity states that the price of a good essential for an individual to achieve his ends (i.e., an inelastic good) cannot remain excessively high for an extended period of time. Human beings act purposefully in the pursuit of their ends, employing certain means to achieve them. If the price of a necessary good rises to the point where it impedes an individual’s ability to attain his ends, he experiences uneasiness.
