Do not cry for me, Argentina. Stay away until you're sure it is close to the bottom.
I wrote sth similar here or in my blog:
Argentina is going to bust when you see:
1. Long lines in basics such as milk.
2. You can get a lot more the exchange from USD in black market.
Socialism is self destructive when there is nothing to give (i.e. the parasites will die when the host dies). US, take notes!
