Sorry to disappoint you, but no you cannot live "comfortably" in "poor countries" for $100,000 for "years". Well, unless you mean like two years.
I lived across South East Asia for more than decade and now live here full time. I have to live on around $20,000 / year most of the time since starting my company. And I do not live anywhere close to what average US / EU citizen will call "comfortable" let alone people from valley.
Stories of rich living for cheap in poor countries its just that: stories. It only possible if you preserve your US salary. For $50,000 post tax a year you can live well unless you have kids that need not a "poor country education".
