Based on having lived here with an Argentine ex partner, I agree with what everyone says but also want to add that they have a different mentality than other cultures with making purchases and spending money.
In the States and Europe, we think it´s very normal and day to day to do things like grab a coffee before work at Starbucks, order take out for dinner a few times a week, hitting the sale racks at the stores, and upgrade our cell phones.
I find that Argentines dont buy things they dont direly need and plan well ahead before making an important purchase, often saying things like ¨I plan to get a new cell phone in 2 months.¨-- In the States, you realize that your phone is a piece of crap and usually have a new one within a week. Also here everything can be bought in cuotas--- even a purchase at the FarmaCity!
That mentality, paired with the fact that families do still help out in many cases, helps them get to the end of the month, although it´s still not unusual for even professionals to only have 50 pesos left around the 27th of the month.
