Most recently, I lived in NYC for 2 years until 2017, large blocks of time in Bs As since 2004 (bought an apt in 2008 and married to a Portena) and now also live part-time in Miami. If you think dining out in Bs As is more expensive than NYC or Miami, IMO you are not well informed. Eating for $25 including tax and tip will not get you much of a meal in in Miami nowadays and much less so in NYC. In my neighborhood Bs As bistros, I can get a steak, salad, and table red for about that (see Bar Norte on Talcahuano). Forget about it in NYC or Miami.I disagree that dinner in NYC is more expensive than in Buenos Aires. That's not true anymore, unless you compare strictly going out to something like a high end steakhouse, then yes, it is cheaper here. But aside from that, an average dish here now is over $10 and usually close to $20 also when you figure in you pay for water, cubierto, etc., so it's always at least $30-$40 a dinner here. In NYC you can eat well for $25. The quality is also much lower here.
Also the time frame isn't right. I'm not talking about 1975, in 2010 I was paying $10 here for a better dinner than I'm paying $40 now. This isn't just casual inflation. The govt. is doing something to keep the dollar low. I'd like to know why and how.
Yes, a meal that cost $10 in Bs As 2010 may now cost a lot more, but I think $40 is an exaggeration. Moreover, if I am paying $40 for a meal in Bs As (with 3 courses and wine I may do so at some of my favorite places, i.e., El Burladero, Rosa Negra, Vasco Francais, Marcelo in the InterSur hotel) then I am having a meal that would cost me almost twice as much at comparably nice places in NYC/Miami. When was the last time you dined out in those cities? You can not eat very well for $25 , all in.
As for the cause of the rapid loss of purchasing power of the USD, see the pieces linked above re managed float. I'm not sufficiently wise to have insight into whether the managed float is good economic policy by the Macri admin. For sure, the government is well within its rights to intervene so as to keep the lid on the USD. If you look through the other end of the telescope, a cheaper USD allows Argentines to travel outside the country (not many could before). However, unless there is a realistic and sustainable economic policy, then as in the past, the peso may reach a level of over-evaluation where it drops precipitously.
Bottom line is that I would love for one USD to buy me lunch and dinner (and a movie ,too), however, that is not very realistic. Nor can I empathize with those complaining that it is "not fair" or "wrong" that Bs As prices are approaching international norms. I can understand and do empathize with those whose life styles have spiraled down to the point where making ends meet is "tough", but that doesn't make varying currency exchange rates wrong or unfair. If you don't like your life style in Bs As, try to find a better place.
