You hit the nail on the head Ed.
The problem with this forum is that they are not any expat, they are upper middle class expats from a rich country, you cant compare upper middle class from a european or north american country with Argentina.
You expect to have the same things here, have the same habits. For example: eating outside in this country, for the middle class, is something atypical. Maybe the upper classes during these last years increased it and do it frequently. But normally eating outside is something for once or twice a month, more is considered luxury.
And like that everything. You expats come to a country like Argentina and expect a first world country. Well, we are not. We had only ten years ago more than the half of the country under the poverty line!! expect a country like that.
And of course the majority of the people you interact are not common people from here, are people who travel, who speak english, educated, etc. That is, upper middle class too, not common argentine people, not low or middle class argentines. Those low or middle class is the social base of the Ks. There you will find real peronismo. Thats why they still, after 12 years, have 40% acceptance. Those who bought a car or a moto, or even a notebook or their first AC. Thats a lot of people. If you go down the social pyramid, they are a lot better than they ever were.
You are upper middle class expats that interact with upper middle class argentines.
