One of the most astute observations of what Trump has to offer comes from JD Vance in The Atlantic: https://www.theatlantic.com/politics/archive/2016/07/opioid-of-the-masses/489911/

“Trump is cultural heroin. He makes some feel better for a bit. But he cannot fix what ails them, and one day they’ll realize it.”

I think Trump has a cathartic release of anger and frustration. He has someone to blame. He has a simple solution that sounds great unless you bother to question if summoning unicorns actually can cure Aunt Sally’s meth addiction or if pouring billions of dollars into “the wall” would actually bring back mining jobs lost to automation. It’s not real, but the idea makes someone feel better for a bit.
