"Many on Wall Street today know that the likelihood of the President making a series of decisions—from launching a trade war to influencing fed policy—that sends our economy downward is unusually high. But, on any given day, the businessperson looks at the numbers that provide clarity (unemployment, wages, G.D.P. growth, the stock market) and sees no reason for today to be the day for despair. Yes, of course, they are all looking, anxiously, at the President, always unsure of what he will do next but knowing something, someday, might be cataclysmic. But before then, perhaps, he’ll do something else, something that helps their business and makes them richer. They don’t know, because there is nothing to base their forecast on other than Trump’s own gut. And that is precisely how he wants it."
