I recommend Eastern Europe or Asia, although I’m sure there is plenty of cheap opportunities South of the border (that is parts of Mexico and down). Really to be a peasant is what you make of the definition. In my opinion people all over live like peasants, but it’s driven home that much more when you displace yourself from the environment and culture you’re used to.
I lived on the Isle of Wight (UK) for 3 months and just walking everywhere and depending on everyone for food and what not felt like a giant stretch for me. I figure everyone is suggesting Scotland and Ireland because of the common language, but since they use alot the words you think you know already differently it’s practically a foreign language in itself.
I’ll tell ya when I first went to Poland in '01 it was like going back in time 20 years. I figure if you go further east (beyond the EU) you will find the comfort level you’re looking for. And don’t be so afraid of the “English language thing” Most kids have already had 2 years of English and use it better than people here. Really if you’re wanting close to nothing then Asia is your best bet. Word is Mongolians will never refuse company and they’re nomads at that. But plenty of Asia and yes Africa too (no thanks) still have community wells or near-by streams and plenty of walking to just do the things you can do here in a 100 sq. ft space.
If I were you I would think carefully on what it is you are really after, you have to know yourself well enough that you know you can tolerate such conditions. When it comes to me, I can live in close to nothing but there better be some pretty scenery to content me… then think about the exchange rate and finally do some searching about those areas, chances are the decision will get made for you- more or less. Good luck!
