Well... In a nutshell the north is poor and south is rich and full of international tourism.
It's something weird of Argentina as a country, 50% of the population lives only in the capital, Buenos Aires. The capital has always had a lot of power (they used to have access to the only port of the city, so they kept ALL the taxes money, while all other provinces received none and were not allowed to have a port).
So, only people in Buenos Aires were rich, everyone else was poor, what made the south "not poor" is the fact that basically nobody lived there (because of "La conquista del desierto" http://en.wikipedia.org/wiki/Conquest_of_the_Desert), people moved south from Buenos Aires to find new customers, find new oportunities and just avoid the "city life".
Also, the south is full of international tourism, cities like Bariloche are full of immigrants and a beautiful Apine-styled architecture, tourists and outsiders are treated quite nicely :)
The north on the other hand has a very native south american culture as there are a lot of immigrants from Bolivia and Peru which have a strong native south american lineage, people is closed-minded and isn't really used to outsiders.
Argentina is great for international tourism I can assure you, cheap and classy, if you handle Euros or Dollars of course, if you ever come visit the country I highly recommend Bariloche, relly, it's beautiful, "El Bolsón" is nice also, a lot of green and nature, also full of international tourism.
If you want tango and city-life Buenos Aires is nice, but as all big cities it has bad parts and good parts :)
