The fact that moving is looked at this way, rather than as a chance for transformation is one of the biggest reasons for the current day malaise. Intra-country movement is in most of the developed world at an all time low, yet it's one of the most straight forward ways to change your life.

Culturally, especially in the US, the idea of packing up your bags, going somewhere else, or even to a new frontier used to be a big part of its appeal even and national identity. This isn't in contrast to fighting for things, in fact people do neither and that's probably related because both involve a level of risk and starting over that's now entirely foreign.

Especially in a world that is changing as fast as ours does now not being able or unwilling to start new or reinvent yourself is a big problem. It was the internal superpower of the US compared to other countries that it had so many people who were just willing to go and build a city, or even a state or a new religion somewhere just for the sake of it.
