Considering the lower cost of living was an important trade-off for some other things that lack here (this is of course a very subjective matter), it's dreamy appeal might be diminishing over some other latin american countries.
However I definitely don't mean to complain, when many people here are genuinely struggling to make the ends meet.
I witnessed how the prices of Coca-Cola increased (both in pesos and dollars) within months, given its popularity Argentinians must be very upset. Talking of restaurants and cafés, notably Starbucks recently raised its prices again just this week, having even a basic brewed coffee seems more expensive than in the US. Local coffee chains aren't offering more affordable options either.
