The march of technology is relentless and likely has more to do with changes in the job market than China or Mexico. Politicians failing to describe the scope of such changes are scapegoating other countries and failing to deal with what is happening. If you order goods from Amazon, you should already know where many of these jobs are going. You should already understand the reduction in book stores and the announcements of job cuts at Macys, Sears and other department stores. Your local store may have already closed. You and I are the problem. We pay for a Prime account and then have the UPS man deliver the goods we used to purchase at the mall.
We prefer inexpensive goods (often produced elsewhere) and we prefer convenience (online purchases). Companies, if they survive, have found they need fewer employees because of greater use of technology. You can blame technology or free enterprise, but we are not going back. The present isolationism promoted by the new administration is the last gasp of an outdated system. There are many new opportunities here, but there are also new challenges. This is why education is becoming more and more important and will not be something that is ever finished for those willing to adapt.
