I could be wrong about this: But I increasingly feel that the major issue for most of these people was economic instability - not making enough to make ends meet. But, out of a feeling of humiliation around saying “im poor” the message instead targets points of blame; either to potentially spare more dollars for themselves, or just genuinely to lash out at a world that’s succeeding without them.

Doesn’t make the approach of their message in any way valid or okay. I’m just explaining that they needed an answer to their struggles. Trump gave them an elaborate lie about it, which to them was better than nothing.
