"All this will involve a curious reversal of the Protestant ethic, which, at least in the United States, is one of the big obstacles to a future of wealth and leisure for all. The Devil, it is said, finds work for idle hands to do, and human energy cannot be trusted unless most of it is absorbed in hard, productive work—so that, on coming home, we are too tired to get into mischief. It is feared that affluence plus leisure will, as in times past, lead to routs and orgies and all the perversities that flow therefrom, and then on to satiation, debilitation, and decay—as in Hogarth's depiction of A Rake's Progress."
