I was born and raised in Seattle proper and a lot of my fellow natives are mad at Amazon workers for supposedly ruining their hometown. But I don't view them as the problem.
Why should I blame them for coming to this beautiful city to seek new opportunities when I don't blame immigrants for seeking new opportunities in this country? What difference should it make if the newcomers are from halfway across the country or halfway across the world?
The people themselves are not the problem, but as a collective they bring problems with them like overcrowding and gentrification. Those are issues that we need to address as a city rather than simply complaining about them and shunning anyone new. Cities rise and fall in this world and the quintessential metropolises like New York constantly reinvent themselves in order to stay relevant. The bleak alternative is falling into obscurity like Detroit and so many rust belt cities.
