I mean at the end of the day I agree with you whole heartedly, but I don't think it's really possible to just brush these people aside and keep trucking when we live in a system that affords them tons of political power.
Unfortunately with trump in the WH their lives aren't going to be getting any better and are just going to get worse. It's one of the biggest shames about the election is that Obama did a lot and tried really hard to help these people, but no one ever heard about it during the election because it was more efficient to direct them to a website and drink margaritas with donors in cali than get off a bus and talk to these people like Obama did.
We just really need to focus more into finding a plausible alternative for these people that actually speaks to them. Problem is, what is it? I don't really have a good answer either. Even infrastructure, the magic bullet everyone keeps talking about, is mostly a bandaid.
