The view from the floor-to-ceiling windows in our room at the new Wynn Encore provides a distressingly clear picture of what’s going on in Las Vegas these days. To the south, there’s a casino project that has ground to a halt, half built, its steel skeleton an outline of a multibillion-dollar dream gone hungry. Across the street, there’s a Modernist chapel, a lonely vigil of virtue on the Strip people seek salvation elsewhere in this town.
