Medicine in Argentina is extremely cheap compared to almost any other country, especially when comparing private hospitals. And it is much cheaper than the rest of Latin America.
The problem this generates is that new equipment isnt being bought as often as it should, which means that the latest technological advances and machines aren't always available.
One of the main reasons for private medicine to be cheap is how the entire system has been reformed to Prepagas profit. Did you know that prepagas get to pay AR$ 10 per consultation to a doctor? And even though we complain about prepagas being expensive, have you ever paid for a full coverage medical insurance in the US or Europe, being a non citizen? Prepagas, for what they offer are also very cheap compared worldwide.
The most expensive private consultation I have heard off in Argentina was AR$ 400, and it was with a world re-known specialist. How much does a consultation cost in the US or Europe?
Also, consider that anyone can get free medical attention in the country.
And to finish my comment, just as another point to compare, last time I checked, a friend of mine in the US, who's a doctor, was paying over U$S 250,000 in insurance per year. Just in case he got sued by a patient. So, to "whatever he wants to earn for a living", he has to add that.
