That indeed is not attractive to a lot of Asian, lifestyle is different, the requirement to tidy the garden, the convinenance of buying stuffs or getting to restaurants, cost of fiber internet (much, much cheaper for high rise than in a house), so on and so forth. 1,500 square feet is plenty for a family already, and things like Phoenix can flood the whole city in a hurricane and ruin your cars, house etc can also be a factor.
And speaking for medical care you have to be too young and naive to not even consider those. Once every 20 years of life saving medical care could be a bit factor, you cannot regret when you didn't get the chance to have the essentially free medical care. And for middle aged middle class, those are legit concerns. Sure you can still be very confident, that's your personal believe.
I just stated that as an Asian what a lot of us think about ever migrating to USA, a few great engineer? Sure individuals could think the house and social welfare in Phoenix is better and decided to pull the trigger, but enough skilled employees to essentially make moving the whole TSMC to USA and ditch Taiwan as a whole? It's easier to day dream, the bottom workforce who can't remotely afford the apartment or house is the ones who can make it work (And why Huawei pulling a few high ranked TSMC ex employee failed to make a TSMC in China). In order to make that happen, the cost to persuade all those employees to bring their family to go to USA will be astronomical, while currently TSMC cost like... I forgot, something like $20,000 a wafer? moving whole to USA will easily jack the cost up to $50,000 or more if you want the same yeild, O, and remember to lower the working hour etc. limitations and the guilds.
