"There has grown in the minds of certain groups in this country the idea
that just because a man or corporation has made a profit out of the
public for a number of years, the government and the courts are charged
with guaranteeing such a profit in the future, even in the face of changing
circumstances and contrary to public interest. This strange doctrine is
supported by neither statute or common law. Neither corporations or
individuals have the right to come into court and ask that the clock
of history be stopped, or turned back."

- Heinlein, Life Line, 1939
