I'd like to weigh in on this if I may. My wife and I are moving to Oahu most likely near the end of this year. We got married in Waimanalo almost two years ago, and she loved it. We were always going to move back to the US, but didn't know where. We decided to visit Oahu again but this time without the "holiday blinkers"! We tried to imagine ourselves as already having moved and what it would be like day to day, obviously as much as you can without having to go to work. We decided that it is the right place for us, and we've been planning as much as we can since then. I grew up in a town just like Waimanalo, so for me it seems like my old town, just relocated a few thousand miles away.
We currently live in London, I've been here since 1998 and my wife has been here for only around 5 years. We live in a two floor house which has been split into 10 apartments, all have approximately 120sq feet of space, and rent in dollars is around $1400 a month. We have no yard, and no space to park a car and so we get around using public transport. It always makes my American friends laugh when I tell them you have to have a license to own a tv here, for real, if they catch you without one they fine you up to something like $2000 (they even have vans that cruise around with gear that can tell if you are receiving a signal, they check it against their license list and bust you if you aren't current with your fees. We have 20% tax on almost everything, and in central London everything is very expensive, even the basics like milk and bread. Before I lost my job I earned just enough to pay rent, my travel and a tiny amount left over to either save or to use for entertainment, about 20% of my salary.
I've been in the UK for about 15 years, and I still find it hard to adjust. Every time I speak my accent gives me away and people know I'm not from around here, let alone my real name! We have racial tension here too, we even have a political party known for it, but they are still allowed to operate. We also have known terrorist supporters who for some reason the UK won't deport because the person in question may be in danger should they return to their own country. I always defend the US when someone here berates her, I always have and I always will. But then again over here the French aren't particularly popular, nor the Germans, nor almost anyone else who isn't British

I lost my job in forensics because the government decided there was no profit in it, and so they closed all the labs down and 1600+ of us became unemployed.
I won't elaborate on how the gun ban is useless, my last job was in fighting gun crime in the UK and business was good

My wife and I are moving to Oahu with no solid job offers, with nothing else but the determination to work our asses off and to do the very best we can. We both have very good resumés, and aren't picky about what we do for work. We are going to try our absolute hardest to make it work, if we fail it won't be because we didn't try. We would rather try and fail than wonder if we could have done it.
My point is that every state, in every country has it's good and bad sides. It has to be what you make of it. Life is to be lived and that includes the hard parts that make you sad, and wish things could be easier. One thing I have learned from martial arts is that there is no shame in not winning, victory isn't black and white.
I wish you the very best of luck in your move to Hawai'i, I hope it's the right fit for you and your family. My wife and I are headed there later this year. God bless us all
