Another fact not mentioned, is that Argentina's government pressured McDonalds to lie on the price of the Big Mac as to appear lower on the chart of the Economist's Big Mac Index (http://www.economist.com/node/21542808).
The Big Mac combo in Argentina is AR$21.50 (approx USD$4.90) and the next cheapest combo is around USD$8.50.
Kragen, I agree it is much more Latin American in the social aspect, but definitely not in the way of doing business and it is much safer to live in as well.
