Yes, the economics around moving have changed a ton in the last 40 years, and people are moving a lot less as a result than they did in prior generations.

Obviously everyone's situation is different so it may not be possible for you, but if you are able to work, focusing on looking for remote/wfh jobs that can go with you in a move can be the difference in being able to move for many since the days of "oh I'll just move and look for a job when I get there" is really only for people who have lots of support and probably connections where they're moving. "Remote" isn't just for software engineers, there are many kinds of customer support, administrative and other roles that don't require specialized training that you could consider. They may not be your dream job but if it gets you out of a lifelong sentence to live in the same spot it might be something to look at if you already haven't. It also can be hard to land any job so acknowledge that.
