Dalton Conley explains the Rich Man’s Burden:
Perhaps for the first time since we’ve kept track of such things, higher-income folks work more hours than lower-wage earners do. Since 1980, the number of men in the bottom fifth of the income ladder who work long hours (over 49 hours per week) has dropped by half, according to a study by the economists Peter Kuhn and Fernando Lozano. But among the top fifth of earners, long weeks have increased by 80 percent.
