Well it sounds like your dad runs a business that bets against the American economy, or he's bad at math and history:

Reagan's economic successes were directly connected to increasing taxes (which he did seven times) and his failures related to disastrous tax cuts.
Like any republican, objective views of the economy are tossed in the garbage in favor of subjective feelings about social issues.
But again, this is meaningless. Trump is objectively a bad businessman, objectively a racist, and objectively not properly aligned with the party he's running for. His only unreversed, stable philosophies have been racist ones. His wall. His Muslim lists.
