Well… a large of the country's becoming depopulated because of the factor Hygro mentioned in the beginning. It's far easier to live here and it's a country where it's every man for himself. There's even a saying: ‘Dios está en todas partes pero atiende en Buenos Aires’ (God is everywhere, but his office is in Buenos Aires). There's a large brain drain and a lot of small towns are dying as it is.How do you conclude that?
Of course, this is partly the result of terrible economic planning, pre-existing underdevelopment of certain areas, and widespread corruption, but still. In any case, the city is too big.
