Agreed, but like how do you fix it? Moving is expensive and difficult the farther away from your starting point you go. That's something that has to be prioritized and even then, it's not always attainable.

Without at least some economic privilege and luck, it's not an option for most people. Certainly there are a group of people who would like to move and cannot because of reasons they find more compelling.

The people who would move but can't, aren't all of the people that don't move far from where they are born. It could be complacency, but it could also be contentedness. The people who stay put usually have much stronger social structures than people who move around, which is not nothing.
