"The result of these moves has been that King County, where Seatac and Seattle are, now has hit an unemployment rate of only 3.3%, a rate not seen since early 2008. While a pizza chain did close shop under the threat of having to pay a living wage, otherwise, business is booming. Rather than being able to claim victory by Seattle losing jobs, instead we find an increase in demand for everything from plumbers to car rental, and an increase of employment as a result.
Indeed, instead of closed businesses, we are witnessing business opportunity expanding across the region."
