Or yes, you could live in Argentina where you won't get a mortgage. You could earn in pesos and realize that taxis are out of the price range of most people here, much less using them all the time. You could deal with health care costs that are increasing 25% a year and can easily cost thousands of pesos a month (or um.. a big percentage of most people's salary) for a basic plan. You could try and figure out how to feed a family in a country where prices are increasing 30% a year along with every other cost but your salary probably isn't.
I love Argentina, I live here, I have a family here but quite frankly, if you live and earn in pesos - it is NOT an easy country to live in, esp in/near cap fed. If you earn or have savings in dollars or pounds, absolutely come and enjoy and yes, it will be a bargain across the board. But understand your reality is far, far away from what most Argentines deal with every day.
