Of course they're self sufficient! You built them a mansion and they get to live there for free!
My in laws live next door in Cambodia in an even more rural village. They have to trek to go to the communal well (if it works). But they have a cell signal and can facebook call/chat w/ family here in the US.
My sister in law was happy to escape working in the rice paddies all day by sneaking over the border into Thailand to work in a sweatshop all day. Manual labor required to grow your own food and process it gets tiring. I guess if that's the only options you have (beyond overseas remittances) you embrace your lot in life, smile, and make the most of it!
We're here in the Bahamas for a month right now kind of in the middle of nowhere. We had the chance to chat with our plumber's 5 year old son for an hour or two while the plumber took that long to complete a 10 minute repair. Life is pretty slow for the 5 year old too. No computer but they have a phone so he's somewhat connected to the world. Activities include swimming and soccer and hanging with his dad. Going fishing in the canal or going out on their boat to fish. Fishing = the way they get protein because wages aren't great, meat is low quality, and store bought seafood is very expensive. Lots of people love fishing (I don't) and the plumber seemed pretty happy about fishing all the time. And the water is full of fish, lobster, crab, etc so maybe it's not much work for a high yield.
I'm glad I have enough $$$ to outsource all of my food production and don't need to worry about where my next meal is coming from or the vagaries of farming (weather, pests, algae/fungus, theft, etc). My paternal grandparents would be best described as a half rung up the ladder from subsistence farmers in the foothills of the Appalachian mountains. They grew or raised most things they ate during the first part of their lives, and sold some of it or bartered it to afford other things. Outhouse, hog house, chicken house, etc all on the property (now all that stuff is gone or in ruins though Grandma was living there at age 90 until moving to a nursing home last month). I'm very glad I've climbed several more socioeconomic rungs from where they are!
