I'm looking forward to seeing the 8th wonder of the world get constructed.
That being said, we actually have 700ish miles of fence/wall down there already. More might be helpful.
I don't really care if the federal government does or does not fund the arts (seeing as funding the arts isn't really a function of government at that level that makes any sense), but ideally the states will get more creative in their own funding activities as a result of this.
