I believe that part (maybe a big part) of our problem today is the belief in "American exceptionalism".  Too many people have bought into the idea, heart and soul.  Yet, much of our past progress may be due to our immigrant work ethic.  If we want to be 'great again', we need to get up off the couch, get a decent education and go to work even if it means changing locations.  We need to accept change, embrace change.  And we should welcome the immigrants who bring so much energy to this country.
