I totally agree with this statement. I always believed that Americans were some of the most fortunate in the world. Sure it has it's fair share of problems but the quality of life is MUCH higher there in most major cities vs. Buenos Aires.
I think the biggest reason before to have moved to Buenos Aires was if you could have taken advantage of an 'arbitrage' type of situation. After the previous crash in 2002 there were several opportunities but for the most part all of those arbitrage situations have totally vanished. Life was not only much cheaper but much easier without all the controls/restrictions/regulations in place now.
Very few ex-pats are truly successful in Argentina these days (especially the ones operating in white). There are several ex-pats that are here illegally. Operate their websites and market to other ex-pats but they don't contribute very much to society in Argentina, they don't pay taxes, etc. To do everything legally in Argentina, while attainable is not really the norm for expats.
From living in Argentina many years I've mainly seen these groups that move there:
1) People that fall in love with someone from Argentina and their significant other can't move to the USA so they are stuck moving there to be with the one they love.
2) People that were laid off or lost their job. They figured they would take a sabbatical and move to Argentina because they heard good things about it or the cost of living was much lower (not now). But the vast majority in this group didn't even take the time to learn Spanish, mostly partied and wasted a possible opportunity to come to Argentina and improve themselves.
3) People that might have lost their jobs but don't even pretend to want to do anything productive. They want to party, they want to goof off and they want to stay here until their money runs out. Then they know they are back to the USA (or wherever they are from).
4) People that are determined to create the next "widget" and get rich in Argentina. They try to start some business but then figure out how brutal it is to do business in Argentina and end up moving back.
5) People that do provide some service but never get their DNI or get legal. They are a perma-tourist and just staying in Argentina year after year. Many of these people are able to work over the telephone or internet so they can earn foreign income and still live here.
6) People that are retired or drawing some stable cash flow in foreign currency or pension and moved here when it was cheap but now that it's more expensive they are having second thoughts. A few bought several properties in Argentina after the crash and although things are more difficult they are still earning very stable income renting out their properties. They truly love Argentina and will probably ride things out there as they have lots of cash flow, no debt and plenty of assets.
7) People that work for a multi-national company or a company that had a division in Argentina where they had the opportunity to transfer to Argentina and get paid in dollars/euros/etc.
There are I'm sure other groups that I'm forgetting but probably 98% of the people I met fell into one of these groups. And most of the people I met already left. Only a small handful of ex-pats I met were truly successful in Argentina in business. A few (including some on this website) but not too many when you look at a city the size of Buenos Aires one of the largest cities in the world.
