Beautiful places, nice climate, different countries, we want them, but do they want us?

I 've been reading that blog, a nice one,  that tells all about different countries where you can retire and live so frugally and nice on 600 dollars a month.Nicely written with great knowledge of a subject. It's a very tempting suggestion. But I am not sure that it is an appropriate one. Of course if you know the culture, the language, traditions, way of life and have dollars to the bargain that could give you a tremendous advantage in view of low local currency exchange. I remember I went to my old country for a visit. I had a good lunch that cost me one dollar. I thought it was nice, but ...  If you come to the country and you have nobody there of your kin, you don't know the language, culture, traditions and you'll be outsider for the rest of population, probably even unwelcomed one. An alien.
I did not experience a lot of discrimination when I came to Canada. But I remember one lady told me,"You came (she meant immigrants) and took our jobs." She blamed me as an immigrant of taking a job from them - non immigrants, local people. And the general policy in Canada is very welcoming towards immigrants. Imagine yourself in a country where every foreigner is an intruder and people openly say so and as soon as you 've learned their language, you understand that. May be they are not going to tell you openly that but they'll try to get advantage, to discriminate you, to cheat you, to steal from you when they can. So no matter how beautiful and friendly this country looks for you - be careful it is still not your country, not the one you know, and used to. Their government might be progressive too - more or less, but they might change that in a flash and a new one might be not so friendly and will kick you out, our just take away everything you have from you, because it is their land and you are an intruder. And tell me, that I am not right. You cannot do it, because I am right. I do not expect any great revolution here in Canada or radical changes in the government, or that people will go on the streets and starts shooting each other, but in other countries it might happen and happens every day in the 3rd world countries. So should I go and risk stability and not very easy and quite stressful life here for the unknown there? I don't think so. But I am immigrant already, I made my choice. What about you? You are still want that adventure, that chance? Well, it's your life, what can I say. Just don't say I did not warn you.
