Typical Trumpism: great identification of a problem to be solved, boneheaded proposal for a solution. (cf. also confront China, use tariffs; control illegal immigration, build a wall).
Someone else with Trump's intuition about what's wrong with America, but without Trump's ego, so that (s)he would listen to experts before deciding on a solution, rather than just making something up that seems good to him (her) would be a great President. Trump should just go away. He had his chance, but his ego (of which his abrasive style is a manifestation) kept him from being a genuinely good President, and all indications are that the problems his ego creates for him have gotten worse over time.
