Reich: Forget Manufacturing Jobs

Robert Reich just wrote an interesting article in Forbes:
It doesn’t make sense for America to try to enlarge manufacturing as a portion of the economy. Even if the U.S. were to seal its borders and bar any manufactured goods from coming in from abroad–something I don’t recommend–we’d still be losing manufacturing jobs. That’s mainly because of technology.
When we think of manufacturing jobs, we tend to imagine old-time assembly lines populated by millions of blue-collar workers who had well-paying jobs with good benefits. But that picture no longer describes most manufacturing. I recently toured a U.S. factory containing two employees and 400 computerized robots. The two live people sat in front of computer screens and instructed the robots. In a few years this factory won’t have a single employee on site, except for an occasional visiting technician who repairs and upgrades the robots.
What does this say about the falling trend in Union membership?
