The secret of Trump's appeal is delusion. His supporters believe Trump will close the borders, remove all the immigrants, tariff imports to the moon, and this will force companies to create millions of middle class jobs with no college requirements, but only for men, while women will be forced to submit to those men in every respect.
It's grotesque. But it's what they think. Meanwhile, the billionaires backing Trump just want to suck up all the wealth remaining in the country.
