Throughout history, poverty is the normal condition of man. Advances which permit this norm to be exceeded--here and there, now and then--are the work of an extremely small minority, frequently despised, often condemned, and almost always opposed by all right-thinking people. Whenever this tiny minority is kept from creating, or (as sometimes happens) is driven out of a society, the people then slip back into abject poverty. This is known as 'bad luck.'
Robert Heinlein, in "Time Enough for Love," 1973
