This is not completly true.
 I live in Argentina and i can buy dollars and i send dollars to outside. You can´t buy dollars with black money, but nowhere in the world can do that.
A lot of people here go to US to Europe, and they can´t buy things there with Pesos, Guess wich coin they use?
The inflations is 20 % and the salary income is up 25% How many countrys can say that?
Men, stop read crap media.
