South America, the best America.
Here is a little secret: Southernmost South America is actually pretty much Europe with good internet + environment + really safe + pretty people + cultured and educated people, and it’s cost of living is really low.
Southern Chile is just like Scandinavia. Southern Argentina is just like Canada green fields. Southern Brazil/Uruguay is what you can find in central Europe. You can even find German/Italian/British/Dutch/Polish towns in those places.
Economy is ok, you can bring pretty much anything and make bank introducing to the local economy. Starbucks for example is not as widespread, so if you create a coffee shop brand yourself you can make some nice bank.
Land is also relatively cheap, you’ll have to ask the local authorities if foreigners can buy land. World Maps don’t represent the actual size of South America; much of its lands are unexplored. But for this reason, everything is far apart. If you work over the internet, just move to a small town, preferably a mountain town or beach town. You can easily rent a big house with 6 or more rooms for 1000$ or if you don’t care about that, a nice home with 3 rooms for 200$.
No immigrants, no terrorism, no risk of war (absolutely no global war had any interest in South America). Violence and crimes stays mostly in the Northern and warmer parts of South America. Also in the really big cities/capitals. Other than that you’ll understand why Nazi Generals moved here to live peaceful lives.
An extra is that you can become untraceable if you want to. So yeah, South America.
