We are in for this ride, at indefinite intervals, for the next 3.75 years. Well, unless congress grows a collective sack (unlikely) or President Trump comes to his senses on macro economics (past experience suggests this is impossible).

They cannot. This is how you can tell Trump was never a real businessman, but rather a TV host and a celebutante. I'd venture nearly all major American business, public and private, depend on stability in the American government. Trump's actions make it painfully clear he is not, and never was, really part of the "business" or "deal making" world.
