My wife is Argentinan, as well as all of her family, and a great deal of our friends. We live in Mexico, and travel to Argentina at least once a year.
The Argentinian exchange rate has dropped in the last year, although not as much as it happened 15 years ago — nor, by far, how it happened 30 years ago. And the local economy is far, far from hopeless— The standards of living in Argentina are quite high, most middle-class people travel outside the country regularly. As a Mexican travelling regularly to Argentina for the last five years, I have seen their life costs go from slightly cheaper to slightly more expensive — and today again slightly cheaper than ours.
My family has their savings partly in pesos, in local banks, and partly in US dollars, in the safe deposits in the bank — AFAICT, they don't have a dollarised bank account. And they have a very decent level of life. My in-laws, as an example, travelled last year one month in Europe, and came to visit for a month in Mexico, without compromising their finances.
This is the second post badmouthing Argentina in Slashdot in the past few weeks. I know I am answering with some (few) personal data points, but that's in the end how reality is: A huge collection of individual stories. And they are far from as dire as you portrait them.
