First I would suggest if you haven't already you should take a look at this thread under expat life: Argentina Teaches 5 Lessons of Happiness.
I think to live here and love it here you really have to be opened minded and ready to deal with some confusing and frustrating things. But if the things you like out weigh the annoyances than it's a good place to call home (or better said adopted home.)
So the things that drive me crazy. First that everything is disorganized. I have been trying to deal with UBA which is a big bundle of craziness. On the other hand though, it's free, which is something you will never find in the US. So I guess the craziness is the price you pay for not having to pay a ridiculous amount of money for an education. But that's not the only disorganized thing. It seems like it's everywhere, at immigrations, the police, the bank, pretty much every place that you have to deal with here isn't well organized. Again, there is an upside though, they are also much more relaxed here. So lets say I make a mistake on a document or I show up late, nobody seems to mind, if I do that in NY they will make a big deal out of it.
If you check out that blog on the lessons of happiness I think a lot of them are true. I have 2 brothers and 2 sisters. I live in a different country and my brothers and sisters are spread across the US, one is in Arizona, two are in Texas, on is in NY. I think here family is more important and you don't see that so often in the US. Sometimes I wish my family was closer so that we could have dinner together or have asados on Sunday like they do here. But I guess too, we all have the opportunity to live somewhere else and that's a very valuable experience, so it's good and it's bad.
I think eating here is a bigger deal. In the US I see a lot of people just go to a fast food place for lunch, they have a half an hour break to eat and get back to work. When I taught some English lessons at IBM the employees had a 2 hour lunch break. We would talk and they would eat and enjoy themselves. They weren't in a big hurry to get back to work. Again, could be good or bad. In the US I think workers are more efficient but have a lot more stress, where as workers here maybe slack off a little but they also take time during the day to enjoy their lunch. (of course not all workers, I have also met people here with very demanding jobs who work long hours!)
I used to always tell my family about what great private health care they have here but for a much lower price than the US. Well, that seems to be changing now that the prices are going up, but it's still pretty good.
I think too that I agree with the blog about happiness when she talks about the Argentines being less materialistic. It seems to me that even when people can afford a good lifestyle they aren't so caught up in material stuff. I see that they invest in things like going out with their friends, having dinner with their family, traveling, taking language courses, starting a new hobby, maybe taking dance or yoga classes. Those are all things that while you don't get anything material from them you certainly benefit in a lot of ways.
Although there are things about living here that make me really sad and don't really have any good side to them. Just the other day I seen a homeless kid trying to sell tissues on the street. Nobody was buying his tissues and he started crying. This woman stopped to ask him if he was okay and he said he was just hungry. I wish I had money or something on me to give him but at the time I just had a couple subway passes and some books on me. I am at least glad that somebody had it in their heart to stop and try to help him a bit. Those type of moments kind of break my heart. But at least they make me realize how lucky I really am!
One thing that strikes me odd about this place is the wages that people get. Obviously, the aren't getting paid enough, but that's not the thing that really confuses me. Recently there was the strike of the health care workers so that nurses can have a base pay of 3,000 pesos. In the US nurses make a lot of money. It's a set rule, the better education you have, the more important your job is the more you make. But in our apartment building the portero makes 4,500 pesos, apparently more than some nurses! I also knew a waitress who made more than an accountant working for IBM. It just doesn't make much sense to me, maybe you could help me figure this one out!
