If you have money, of course, lots of countries have enclaves of affluent Americans/Europeans where they can live with others just as if they were home.
For example, Lots of such young folk in Makati in Manila area. Drugs, sex and rock and roll, but not much for families. The problem is loneliness.
And there are enclaves of expats who retire here because it is cheaper to live, or because they married a Filipina spouse. There is even a special retirement visa for those who put 10 thousand dollars down .
