I'm an African American software engineer who grew up in a medium size factory city (100K people). I went to a private predominately white school and church growing up, of course now I work with people of all ethnicities in a major metropolitan area,so I thought I thought I was the farthest thing from being prejudiced.
After reading articles like this one during this election cycle, I had to take a step back and realize that I was also guilty of looking down on the people he described as the Trump supporter and that I had my own prejudices. I've never had any reason to interact with poor people from any other race and didn't think about their perspective. Everyone I interacted with that wasn't Black were either people I went to private school with (meaning by definition they weren't poor), worked with (meaning other IT people), or lived and worked around (the top 20% of income earners).
And the article is correct. At least politicians and the media pay lip service to inner city poverty, no one does even that much for poor people in small towns. If I were part of that demographic I would be going for a politician too that wanted to blow the whole thing up.
