Timothy Egan in today's New York Times:
Seattle officials are trying to decide whether an entire city can raise its minimum wage to $15 an hour without killing a robust economy, the social service agencies, and the numerous immigrant and family businesses that pump new blood into old places.
All the evidence shows that, yes, they can — but only if they do it right, and do it gradually over many years. If they rush into it, as the zealots favor, they could hurt the burgeoning raise-the-minimum-wage movement around the country and deprive Democrats of a great voter stimulant for the midterm elections.
The choice, as Egan sees it, is between Seattle becoming "a model for the rest of the nation" and Seattle becoming "a cautionary tale, used in scare ads by the forces of regression."
