Seattle is a town that appears split upon the idea of Amazon. Yes, it's brought a lot of business into the area that wasn't there before, but it's also brought a lot of homelessness. Even with the jobs, Amazon's not paying enough to get its employees into relatively low income housing in a city that's having a huge house boom. On the other hand, Seattle has been doing a lot to combat urban sprawl, which will effectively drive up housing prices without the presence of Amazon in town. But it's easier to blame Bezos than it is to go after like-minded politicians at the local level, or even include them and their policies in the discussion.
Amazon warehouse people are paid peanuts. Engineers are highly paid and driving up the housing costs.
