>I’ll never understand how someone can like a place so much, they go out of their way to hunt for a new job, pick up and move to an entirely new city, and then complain or refuse to do the things which it takes to maintain that which made you fall in love with a place.

Because most people are consumers, not creators, and when an excessive amount of consumers enters a space that previously had a balance between consumers and creators, the prices get bid up and the imbalance results in a situation where people drive 15 minutes to go to the big box store.

The consumers wanted to consume the convenience of the little shops, but not in sufficient quantities to continue to make it a viable business in the face of rising demand from other consumers coming in also to consume the convenience of the little shops. Hence you end up at a new economic equilibrium where the big box stores are the only ones left.

Then, if society is lucky, the intial and boundary conditions will allow for a new place to reach a balance between consumers and creators, and rinse, repeat.

This is also a little bit related to this theory:
