When You Can't Afford Sleep - The Atlantic: McCalman’s life reveals a particularly sorry side of America’s sleep-deprived culture. Though we often praise white-collar “superwomen” who “never sleep” and juggle legendary careers with busy families, it’s actually people who have the least money who get the least sleep.
Though Americans across the economic spectrum are sleeping less these days, people in the lowest income quintile, and people who never finished high school, are far more likely to get less than seven hours of shut-eye per night. About half of people in households making less than $30,000 sleep six or fewer hours per night, while only a third of those making $75,000 or more do.
