I know a guy that instead of retiring at 50(after 30 years), the company offered him a position in SheKou China. He got a work visa somehow and has been there 10 years. He took about a 20% wage cut from the NYC metro area. Now he lives in a mansion and has two full time servants.
SheKou is near Hong Kong and as Modern as any major city here in the US.
I would consider Thailand. It's very inexpensive and the people genuinely like Americans. At 40ish Baht to the dollar, your money goes a long way. Other than the smell, Bangkok isn't so bad, but you could easily move into the country or near one of the resort areas and live very well on just SS alone if nothing else. Of all the Asian countries I've visited, Thailand is my favorite.(and no, not because of any sex business or any such thing).
While many of us here do not care for lawyers, my recommendation to you is to get legal advice regarding the implications of living in Thailand. We did just that - we had both one in the US familiar with Thailand do it and one in Thailand as well. Bottom line is, unless you are willing to forgo major protections of your consumer rights, your property rights (even in New London! LOL), your estate planning, and other things we take for granted here, don't do it! We took a serious hard look at it and concluded NFW when the risk exposure became apparent. All you need to do to see the risk is to play a few scenarios of stuff going wrong. The only people who I would not strongly advise against doing it would be people with no kids, small estates and who really have essentially "nothing to live for" in the US. Seriously ... that was our conclusion.
