The angry white middleclass doesn't understand the nuances of your question. They don't know who Horatio Alger is and they can't find bootstraps on their swamper boots. All they know is Jr. And his pregnant girlfriend are shacked up in the spare bedroom because the two part time jobs they work can't cover the costs of rent in an apartment.
They see the writing on the wall and instead of taking vacations with their retirements savings, they will be staying at home, raising their grandchildren and subsidizing their children's lives for eternity. They don't necessarily see Trump changing things as much as they see him being the delivery system for blowing up the establishment whom they blame for their current status.
They are pissed off and "two Corinthians" doesn't matter to them. Actually, it's really quite funny.
