Did the incoming administration have anything to do with Ford’s decision? Can political pressure change G.M.’s strategy? It hardly matters: Case-by-case intervention from the top is never going to have a significant impact on a $19 trillion economy.

So why are such stories occupying so much of the media’s attention?

The incoming administration’s incentive to engage in fake policy is obvious: It’s the natural counterpart to fake populism. Mr. Trump won overwhelming support from white working-class voters, who believed that he was on their side. Yet his real policy agenda, aside from the looming trade war, is standard-issue modern Republicanism: huge tax cuts for billionaires and savage cuts to public programs, including those essential to many Trump voters.

So what can Mr. Trump do to keep the scam going? The answer is, showy but trivial interventions that can be spun as saving a few jobs here or there. Substantively, this will never amount to more than a rounding error in a giant nation. But it may well work as a P.R. strategy, at least for a while.

Bear in mind that corporations have every incentive to go along with the spin. Suppose that you’re a C.E.O. who wants to curry favor with the new administration. One thing you can do, of course, is steer business to Trump hotels and other businesses. But another thing you can do is help generate Trump-friendly headlines.

Keeping a few hundred jobs in America for a couple of years is a pretty cheap form of campaign contribution; pretending that the administration persuaded you to add some jobs you actually would have added anyway is even cheaper.

Still, none of this would work without the complicity of the news media. And I’m not talking about “fake news,” as big a problem as that is becoming; I’m talking about respectable, mainstream news coverage.

Sorry, folks, but headlines that repeat Trump claims about jobs saved, without conveying the essential fakeness of those claims, are a betrayal of journalism. This is true even if, as often happens, the articles eventually, quite a few paragraphs in, get around to debunking the hype: many if not most readers will take the headline as validation of the claim.

And it’s even worse if headlines inspired by fake policy crowd out coverage of real policy.

It is, I suppose, possible that fake policy will eventually produce a media backlash — that news organizations will begin treating stunts like the Carrier episode with the ridicule they deserve. But nothing we’ve seen so far inspires optimism.
