I wouldn't put much faith in Europe. The terminal decline here is going on there, just at a slower pace.
Options I would consider:
Latin America (Ecuador or Chile mainly). Depending on country, there's stability to the point of constricting stasis. Which sucks if you're native and poor, but means that if you arrive with good money by local standards, you can expect things to more or less go the same way for the rest of your life.
India. Politically stable if you aren't a Muslim, good healthcare if you have Western levels of money, plenty of enclaves of safety. In coming years, internet, AC, and permanent power without outages will be more and more common across the country. Mostly I suggest it as an example of an up-and-coming, democratic society, which is likely to remain relatively free provided, again, that you aren't a Muslim.
As for specific places, there are some old British hill towns up in the highlands where the climate is an eternal spring, and there won't be constant crowds. If you want peace, quiet, and stability, probably a good place to check out. You also don't need to learn a new language, because you can always find someone who speaks English.
Sri Lanka is good too. Despite recent terrorist attacks, it's generally safe, stable, pluralistic and tolerant. Even if shit hits the fan again with the Tamils, most of the country will remain safe, especially if you aren't from one of the rival ethnic groups. It's a popular expat destination for a reason.
Any country in SE Asia. If you get out of Bangkok, Thailand is stable, relatively free, and not full of peak degeneracy. Malaysia has better economic prospects, but I'd be worried that it will start copying China in the future. The Philippines can also be pretty good for an expat, and if you are the Christian Ernst, it's Christian. Baguio is a sizable city in the mountains, with a temperate highland climate, and a long history as a livable expat center.
