"The longer we stay stuck waiting for a savior to bring back our jobs, the longer we are denying ourselves the opportunity to move forward towards progress."

In some ways, I understand Trump supporters who feel alarmed by the changes our country has undergone in the last 50 years — demographic changes, technological changes, and jobs changing. I see the appeal of Donald Trump's promises for those voters who fear the restructuring in our country. They have worked hard to find their cheese, and now the cheese is gone. Like me during the restructuring, they are having a tough time with change.

Trump has told his supporters that immigrants from Mexico, China and other countries have stolen their jobs. That rhetoric is wrong. He has promised to bring back those jobs, but the truth is that industries in our country have changed, and some jobs no longer exist. Technology has brought about progress and change, but in the process it has left some people displaced and others unequipped to take advantage of the "new cheese."

Take the metal industry. Roles held by people to set casting machines and operate core-making machinery have declined by 25 percent, according to the Bureau of Labor statistics. Instead of a metal worker being paid an average of $30,000 a year, companies have adopted machines that use computer numerically controlled technology (CNC) to lower production costs and improve product quality. Another example is postal workers, where jobs are projected to decline by 34 percent by 2024. These jobs are being pushed out by the nation's reliance on email and online bill-paying services.

Some industries, of course, do face foreign competition, but instead of looking into the past to find our future, we need to look ahead. We need to stop blaming immigrants for stealing our jobs. Times are changing. Instead of focusing on finding a scapegoat and building a wall, we should focus on finding solutions and giving people the skills necessary to succeed in the new industries.

The longer we stay stuck waiting for a savior to bring back our jobs, the longer we are denying ourselves the opportunity to move forward towards progress.
