Our population increased by tens of thousands in the first year as a result of the announcement by Amazon that Seattle would be the permanent HQ. Following that, tons of cheaply made, overpriced housing was put up all over the city. Businesses were priced out and knocked down to make way for the shitty people-boxes.

Seattle is a geographically constrained area that was already at capacity. Blue collar workers and service industry folk were priced out and pushed into surrounding areas. Traffic and congestion increased. Homelessness skyrocketed.

I would agree that the issue is widespread, but in this case, correlation and causation line up.
