Well, there are some jobs that working class could in theory transition to.  Health care would be a big one.  The population is aging now and there is no need to create a new industries, but many blue collar men refuse to go to such jobs because they consider it woman's work.  And Obama created some of his own problems.  I didn't appreciate how condescending he could be to his political opponents.  (Has he sent Romney an apology yet for mocking him in the debate in 2012 for saying Russia was a geopolitical threat yet?)

And trade is a good thing.  It is good for many American industries like agriculture.  It is good for US consumers.  TPP would be good for US strategic interests in the Pacific.
