If Donald Trump believed in anything aside from his own instant gratification -- he does not... But if he did, it would be Herbert Spencer's idea of Social Darwinism. In nature, the strongest and fittest survive, and in human nature, only the strongest and fittest deserve to rule over the weak and survive in luxury at the top. The weak are here to feed the strong. They are like a sub-species to be taken advantage of because they are weak. In Trump's world, gullible evangelicals were put here for him to use in the exact same way that they are used by the predatory prosperity preachers he so admires. William Jennings Bryan feared men like Trump and warned us they were coming. And for that bit of wisdom, he deserves some credit.
