Many people in the First World assume that Buenos Aires is a cheap place because it is in South America, but many places in South America have actually higher costs of living than Europe/North America, with lower incomes. An apartment in a nice neighborhood with a reasonable size is ~USD1000[1], while local income for a Sr Software Engineer is around ~USD27K[2] (sounds low even for BsAs standards, but not outrageously so) and taxes are outrageously high (over 50%[3] for an individual, 137.4%(!) of the profits for companies[4]).
