What does the first world have to do with anything?
No country is perfect. Every country on the planet has its pros and cons.
So many expats literally "dying" to live here. Their must be something good going on here, that they want to live here.
So many students from all over South America studying here and taking advantage of the free education.
So many expats and mercosur residents getting free medical treatment here..
The list can go on and on. If everything was perfect here, then the economy would be booming and 1 usd would have been equal to 3 pesos and perhaps lot of things would have been different then..

The best business to do here is service orinted business where you do not have to import or export anything..Where all you do is sell your skills ..where you do not have to open a shop or a physical office. To have skills which are in short supply here or in the continent. If you have that, you will have the ability and be able to be, what you want to be.
