Yep, and one of them is the insidious nature of RW media. We all understand that there are a huge number of disenchanted (mostly white) middle- and lower-class mainly blue collar workers in this country who are unhappy about jobs, upward mobility, the American dream. RW media -- and politicians -- capitalize on this by showing them enemies to blame: The Democrats, China, globalization, etc. We would be much better off if we would explain that this is the nature of capitalism and a maturing economy. Then instead of assigning blame, we would instead fix it by offering the kind of education that would allow these guys to move into different career paths. Robotics have taken most manufacturing jobs; teach the willing how to maintain and use these tools. Health care is a growing field; offer education that doesn't require a four-year degree: occupational therapist, patient care tech, radiology tech, pharmacy tech, etc. Skilled trades are always looking for people. There is no reason why government and industry cannot team up to train and provide good paying jobs.
Fanning the flames of disenchantment is not helping these people, or the nation. It's only dividing us.
