Yesterday my son, who works in the Chicago Loop, saw a woman on a bicycle get hit by a car. She wasn’t seriously injured, but she was knocked to the ground, dazed. He ran up to her to see if she was okay and pulled out his phone to call 911 — but she quickly, urgently said, “No! No! I can’t afford to go to the hospital!” And after taking a moment to gather herself, she got to her feet, picked up her damaged bike, and wobbled off.

And so my son stood there on the corner, surrounded by the glories of Chicago’s architecture, the superb expensive shops on the Magnificent Mile, the wealth that fairly pulsates from every building, and reflected, as one well might, on American Greatness.
