According to legend, Grigory Potemkin, one of Catherine the Great’s ministers (and her lover), created a false impression of prosperity when the empress toured Ukraine. He supposedly did this by setting up fake villages, or possibly just facades, along her route, then dismantling them after she passed, and setting them up again further down the road.

There probably isn’t much if any truth to the story — among other things, Catherine was too smart and tough-minded to be that easily deceived — but never mind: the legend has become a byword for the general idea of prettifying reality to please a tyrannical ruler. And it seems highly relevant to some of the economic “news” coming out of the Trump administration the past few days.

Just to be clear, the U.S. economy is still doing quite well overall, continuing the long expansion that began during Obama’s first term. Those of us who thought the economy would be hurt by political uncertainty have been wrong so far.

But Trump’s actual policy initiatives aren’t doing so well. His tax cut isn’t producing the promised surge in business investment, let alone the promised wage gains; all it has really done is lead to a lot of stock buybacks. Reflecting this reality, the tax cut is becoming less popular over time.
