If America had a parliamentary system, Donald Trump — who spent his first full day in office having a temper tantrum, railing against accurate reports of small crowds at his inauguration — would already be facing a vote of no confidence. But we don’t; somehow we’re going to have to survive four years of this.

And how is he going to react to disappointing numbers about things that actually matter?

In his lurid, ghastly Inaugural Address, Mr. Trump portrayed a nation in dire straits — “American carnage.” The real America looks nothing like that; it has plenty of problems, but things could be worse. In fact, it’s likely that they will indeed get worse. How will a man who evidently can’t handle even the smallest blow to his ego deal with it?

Let’s talk about the predictable bad news.

First, the economy. Listening to Mr. Trump, you might have thought America was in the midst of a full-scale depression, with “rusted-out factories scattered like tombstones across the landscape of our nation.” Manufacturing employment is indeed down since 2000; but overall employment is way up, and the unemployment rate is low by historical standards.

And it’s not just one number that looks pretty good: Rising wages and the growing number of Americans confident enough to quit their jobs suggest an economy close to full employment.
