This thread is pathetic. Yes a rising minimum wage could cost job, if Seattle was dominated by low wage and low skill production jobs. Instead most people who work for minimum wage is in the service sector, and service job are where people need it. The suggestion that McDonald would move their shops from the more densely populated parts of Seattle to outside the city limit because a raise in minimum wage are as pathetic as it's idiotic. "The minimum wage is rising, let move away from our customers to a thinly populated area, that will teach them!".
1) As Ernest suggested, most of this movement will happen on the margin, with most of the movement being around the outskirts of the city. Obviously downtown Seattle McDonald's won't move, but just inside the city limits McD's might become just outside the city limits McD's
2) There is a huge incentive for low wage employers to shift from labour to capital i.e. self serve pop machines, auto-checkouts etc.
3) At $15/hr, this increase affects a lot more than fast food workers & grocery store clerks.
