Amazon.com will be opening a fulfillment center in west Phoenix.  The 300 jobs will include both warehouse and management jobs.  Any additional jobs added to the economy generate mare jobs as the money trickles its way into the local businesses.  In addition job creating in the west Phoenix valley is good.  It means more people will not have to drive into the Phoenix to work, of course, assuming these jobs are not taken by residents of Tempe or some other city miles away.  More jobs are always a good thing and maybe we'll even get our stuff faster than it already comes.
