The WSJ, Bloomberg, etc., have all pointed out a few things:

1. Trump is an individual businessman/entrepreneur, (the most self-reliant kind - a developer) but has never had a boss, answered to shareholders, etc.

2. The LAST thing the CEO of a publicly traded company wants is to wake up to a 3AM tweet from the president/elect threatening tariffs (taxes) on your company based upon a simplistic assessment of but one action of your organization (opening a production facility in another country)...several companies have seen their share prices decline because of this...

All in all, the business community's belief that "one of theirs'" is now president is turning out to be not such a good thing...
