...a leading explanation for the disappearance of the middle class is "ongoing automation and off-shoring of middle-skilled 'routine' tasks that were formerly performed primarily by workers with moderate education (a high school diploma but less than a four-year college degree)." Routine tasks, he explains, are ones that "can be carried out successfully by either a computer executing a program or, alternatively, by a comparatively less-educated worker in a developing country."
The culprit, in other words, is technology. The hard truth-and you don't see it addressed in news reports-is that the middle class is disappearing in large part because technology is rendering middle-class skills obsolete.
People say America doesn't make anything anymore, but that's not true. With the exception of a few short lapses, manufacturing output has been on the rise since the 1980s. What is true is that industrial robots have been carrying ever more of the manufacturing burden on their steely shoulders since they appeared in the 1950s. Today, a Japanese company called Fanuc, Ltd., has industrial robots making other industrial robots in a "lights out" factory. (That's the somewhat unsettling term for a fully automated production facility where you don't need lights because you don't need humans.) That's where we're headed.
It's not just manufacturing, either. Automated call centers are replacing customer-service agents. Automated checkout stations are replacing grocery-store clerks. When the science of computer vision advances sufficiently, we'll have algorithms, not humans, evaluating X-rays at airport security checkpoints and screening user-generated content for sites like Facebook.Read more.
