Am I a complete weirdo for contemplating moving to America?

I would be gone without a doubt. Both countries have their problems but, if life there is not good, you can always come back.
If you don't try, you'll never know and will always wonder if you missed a big opportunity

Money makes a huge difference to comfort and happiness. Useless to pretend otherwise. Do the calculations once you consider healthcare, retirement, and education (yourself and any children).

However, moving to a country that is incredibly hostile to immigrants as the country shifts towards a dictatorship is risky.

If you are white - you probably won’t be targeted by ice. However, is your social and political history clean? Are you at risk of being denied entry for anti-Trump expressions (memes, jokes etc)? Are you ok meeting such restrictions on your expression going forward once you do live there?

Do you have kids? Are you comfortable them living under such restrictions? Would they live well under such restrictions? Or would they join a protest / say the wrong things / post memes online. Even if you every intent of doing everything by the book - are you confident you won’t make mistakes?

For every legal immigrant targeted by ice there’s no doubt a very large number going about their lives fine. But that risk is there. The South Korean workers currently suing ice had visas. Other cases have been legitimate minor paperwork errors that should result in a fine - not incarceration in conditions that violate human rights.

My country is far from perfect in our treatment of immigrants and asylum seekers. We have violated human rights, and there are documented cases of admin errors leading to illegal deportations. Our govt has not been perfect in their response. But Trump/ICE is next level.

Its a great opportunity. If I was younger and had the opportunity, I would do it. Don't let the nay sayers put you off.
Yes there is crime and guns etc but its getting that way in the UK now as well.
Go for it!!

We own a house in the states, but in SW Florida - I wish it was in Connecticut. I’d definitely consider living there, but not with school age kids as I’d be too worried they’d get shot at school.

In a blue state I probably would. I spent my childhood roughly equally divided between the States and the UK and hands down the States was a better place to be a kid (if you have money). DH recently turned down a job offer in Palo Alto because even though on the surface it looked like more money, once you accounted for the obscene cost of living we'd have been no better off. That's really area dependent though, and Connecticut is lovely.

You can always come back......

Oh I love Connecticut! I grew up in Boston. My sisters still live there. I’d go for it - you can always return! Give it five years to really settle in. It’s liberal in the east and while country politics are dire you won’t have much trouble in affluent suburbia. What would YOU do? Your kids are your in to the community. Where I grew up it was unusual to go to private school as state were very good, but I guess it depends where exactly you are. Get volunteering if you won’t be working. There’s probably an English ex-pat community there too - my mother joined a society which was great for meeting people.
By the way I think the education system there makes much more sense than here. Non exam based, broader curriculum until 18, leaving options open, and when you apply to uni you get a yes or no, not this anxiety inducing ‘conditional’ offer. It is of course American-centric, but that’s to be expected. Good luck!

Many, many people live very happily in the USA. No reason why you can’t be one of them.
Go for it, if it doesn’t work out you can always sell up and move back.

You couldn’t pay me any amount of money to raise my children in America in the current climate. But ultimately, it’s whether the surface/material things such as house & money are enough of a sway for you personally.

I can only speak for myself but absolutely no way. I don’t even want to go there on holiday. You sound like you’re convinced though.

Personally it would be Canada although I'm not sure I could cope with their winters.

If you like the area and you like your time there why not

my family live there and just getting on with day to day life like we are here not everything is impacted by having a mad president (though my dad has postponed travelling but it’s not essential travel)

the US has the best and the worse of the western world life can be great many of my family have a really good standard of living (not so much you younger generations and facing same issues as here)

I personally never feel at home there so not moved over there (much to my dads amazement) but I can certainly understand the appeal

What about the far east

with the US - have you actually done the maths? No point in living a big house if you can’t even afford dental, doctor or hospital care, or schools.

If I didn't have children, and it would be for a specified length of time - yes I would go for it.

But with kids? No. It was hard enough making the decision to move house, uprooting them, and that was within the same postcode! I know Connecticut isn't known for being particularly right wing, but honestly I genuinely think it's a risk I am not willing to take.

You could learn a language. Spanish is very easy to learn to a conversational standard.

Just loads of racists.

I would consider Australia or New Zealand. Great quality of life and no guns.

In your position I’d try and go to Singapore I think

3 x the salary doesn’t work as a comparison because living in the US is so much more expensive. Even with work health insurance my friends there all have to top up their insurance to get anything like a decent level of cover. That’s $1000 a month for a family straight off the bat. Things cost more in the US too - food is more expensive in the supermarkets there. And then there’s the politics…

If you split up and the kids are settled you won't be able to move out of the USA with them. Will you be able to work there? If not then you wouldn't be able to support yourself to stay after a split - you're making yourself vulnerable to living in a different country to your children.

By myself or as a couple, sure, maybe

With school age kids, nope

Hell, no. A thousand times no.

With everything going on, this sounds great. Never feel guilty because you have this opportunity because there are many who would jump at this opportunity.
