Affluence = time more valuable = multi-taskingSo being busy can make you rich, but being rich makes you feel busier still. Staffan Linder, a Swedish economist, diagnosed this problem in 1970. Like Becker, he saw that heady increases in the productivity of work-time compelled people to maximise the utility of their leisure time. The most direct way to do this would be for people to consume more goods within a given unit of time. To indulge in such “simultaneous consumption”, he wrote, a chap “may find himself drinking Brazilian coffee, smoking a Dutch cigar, sipping a French cognac, reading the New York Times, listening to a Brandenburg Concerto and entertaining his Swedish wife—all at the same time, with varying degrees of success.” Leisure time would inevitably feel less leisurely, he surmised, particularly for those who seemed best placed to enjoy it all. The unexpected product of economic progress, according to Linder, was a “harried leisure class”.
