Bryan Caplan quotes Thomas Macaulay writing to us from 1848
We too shall in our turn be outstripped, and in our turn be envied. It may well be, in the twentieth century, that the peasant of Dorsetshire may think himself miserably paid with twenty shillings a week; that the carpenter at Greenwich may receive ten shillings a day; that laboring men may be as little used to dine without meat as they are now to eat rye bread; that sanitary police and medical discoveries may have added several more years to the average length of human life; that numerous comforts and luxuries which are now unknown, or confined to a few, may be within the reach of every diligent and thrifty workingman. And yet it may then be the mode to assert that the increase of wealth and the progress of science have benefited the few at the expense of the many, and to talk of the reign of Queen Victoria as the time when England was truly merry England, when all classes were bound together by brotherly sympathy, when the rich did not grind the faces of the poor, and when the poor did not envy the splendor of the rich.
My working theory is that as people age their opportunity set shrinks. So, it is true that the world is a darker place for me than it was twenty years ago. It could scarcely be anything else. It is, however, a brighter place for young people coming of age today.
