That's a euphemistic way of saying we are more automated. For political reasons it is always phrased as a compliment to the remaining Americans not yet automated out of a job.
Not euphemistic. It is the terminology used by economists. And that is correct. America is more efficient than anyone else with closest competition from S Korea.
Automation, in a rational freemarket system leads to more jobs at all levels. That has been true since the beginning or the Industrial Revolution.
