We've got enough problems with the consequences of being the national capital making us a "one of a relative handful" kind of "company town" to be sure. Whether having Amazon around would make that situation better or worse, I don't know. Also, we - as a country - still like our labour unions somewhat more than seems to be the case in the States and we're redeveloping an appreciation for the details of our tax laws. If fear of Trump becomes enough to make Amazon go along to get along up here...?
