Other innovations suggest how, despite the protestations of employers, a tight low-skilled labor market can spur modernization even in the service sector: Automated switches have replaced most telephone operators, continuous-batch washing machines reduce labor demand for hotels, buffet-style restaurants need much less staff that full-service ones. As unlikely as it might seem, many VA hospitals are now using mobile robots to ferry medicines from their pharmacies to various nurse's stations, eliminating the need for a worker to perform that task. And devices like automatic vacuum cleaners, lawn mowers, and pool cleaners are increasingly available to consumers. Keeping down low-skilled labor costs through the president's vast new guestworker plan would stifle this ongoing modernization process.
