"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."
I liked reading him when I was a kid. Maybe I should start again. Thanks to Nathan for pointing me to it.
