As a developer, Donald Trump always wanted the biggest, flashiest, and most expensive of everything: buildings; golf courses; casinos; whatever. It is safe to assume he still does.
The irony is that he is the head of a party which believes with all of its heart and soul that a dollar given to the public sector is a dollar inevitably wasted. The tax cut is a perfect example of this philosophy in action. As a result, there will be no money for Donald Trump bridges, highways, or airports. If any new monuments are created, it will be done by private individuals, and they will bear the names of their creators, not Trump.
Oh well. He can always start his own war if he wants a monument. No mere developer can do that.
