Seattle would fight that tooth and nail. Amazon could simply say they are thinking of withdrawing from the city and Seattle would throw tax breaks at them that would make NYC's concessions to amazon look pale in comparison. See Boeing as an example. Cannot have an exodus of talent, that is bad news bears for any major city (see Detroit as a historic example)
Nope, any noise of tax break to super rich company like Amazon in politically charged city like Seattle will raise huge public outcry and no one really want that.
Another thing to understand in asking RTO Amazon gets implicit support of city/builders/ tons of other vendors. Further it should be no surprise (but it is!) that multiple hundreds of thousand dollar a year earning employees are going to get no sympathy on their plight from public at large. So why should CEO care at all on this issue.
