Pardon me for being optimistic here.
At the end of the day, ignoring all the news and talking heads, so what? Did the U.S.A. crash and fail in any way so far? Is the economy in the dumpster? Are people hungry for food? What?
This is a testament to the U.S.A.'s structural strength. It will come out of this stronger and better. Trump will be replaced. Another idiot will take his place. The system will continue to work.
Even more optimistically, (hey I'm an investor, what can I say...) this might wake up the public to the fact that the world is changing and some things will have to change with it. Better sooner than later.
