This isn't about age, and I'm not sure why you're even framing it that way.

The crowding, costs, and congestion in Seattle have increased very significantly with Amazon. There have been very ugly social side effects as well.

Amazon's employees, most of whom are out-of-towners, don't need to live in Seattle as much as the people whom they're displacing. Basically, a lot of the Amazon transplants could work remotely or find jobs in other cities.

This was all entirely avoidable.
