Sure, I work in tech, but like plenty of other people who work in tech, it's not as simple as "just move somewhere else." I've only ever driven through Texas, and it's a big state, so I can't comment on what it would be like to live there but I properly detest the climate in Florida, which I'd find impossible to tolerate, and the topography there is extremely uncompelling. Still, I suppose who doesn't love a bit of Miami from time to time? But even ignoring those relative trivialities, there are a bunch of serious issues I'd have to negotiate to make any major relocation a reality:

1. I live in the UK. Sadly I can't just up and move anywhere I choose. Even more frustrating, since we left the EU I can't even just up and move anywhere I choose in Europe (not that restrictions-wise it's much better there at the moment).

2. My close family are all in the UK and, although the rules have made it hard to see them as regularly as I would have liked over the past 2 years, it's been a lot easier (and less costly) than it would have been had I "just moved somewhere else", and I want to continue to be nearish to them.

4. My girlfriend and her close family live in the UK. I'm not leaving her to move somewhere else, and especially not to move to Florida - WTF. Just as importantly I can't see her being keen on living that far from her family.

5. Most of my friends live in the UK, either close to where I live now, or close to where my parents live. I could start again somewhere else but, overall, I'm fairly content with my life. Ditto my girlfriend's friends.

6. My current employer places a 45 day limit on working abroad for tax reasons. This isn't insurmountable. I could find another job but finding another job is another barrier, and I quite like my current job.

7. I have a house that I'm part way through refurbishing. I'd have to figure out what to do with that but, whatever the outcome, that decision will require a significant investment of time, or money, or both. The reality is it would be a trade-off between the two but, in any event, would represent a substantial investment that due to the need to act quickly might well outweigh what I'd invest if I were less constrained by time.

8. I've never wanted to live in the US, though I like visiting, and I'd certainly want better employment conditions than I'm likely to find there: i.e., sensible amounts of holiday, decent employee rights, not to mention public healthcare.

Yes, if I was still 28, single, had my whole career ahead of me, and hadn't yet bought a house, I could simply up sticks and leave, as long as practicalities rather than relationships were my major driving factor. But it's not so simple, and the fact that I work in tech is basically irrelevant because the only part of the equation it simplifies is the "getting a job" part, which isn't even the most important aspect of said equation. As an aside, somebody like Joe Rogan can move from California to Texas relatively easily because he's a jetsetter and all his mates are jetsetters so he pretty much only gets the upsides from that move (not a criticism: with the kind of money he has, I might well see things differently too).

But far more important than all of that, your comment plays hard to the point I was making: why the hell should I give everything up because, in some part, of a bunch of people who won't see sense? What difference does it make whether that's because of rules and restrictions, or because I've had to walk away from my life and start again because of them?
