You've been told Trump has no program, no proposals to make things better. Maybe that was a little true, it is no longer. Politico has the complete text of Trump's speech in Pennsylvania which lays out his economic policy.
His policy has to do with being a tough customer and competitor in the world market. It puts the interests of Americans first. It advocates reprisals when other nations invoke protectionism, no more turning the other cheek.
Will it work as described? Probably not ... few policies do, whomever promulgated by. Is it worth trying? In my opinion, yes.
If you don't have the patience to read Trump's whole speech, John Hinderaker at Power Line has done a decent summary with excerpts.
