Yes, it's very cheap in Argentina. Even if Argentina ever could truly dollarize (I don't see that happening anytime soon). It won't be expensive like it was before.
I'm not sure if Argentina is cheaper than Bangkok. I was just there not long ago and it was very very very very cheap. If it weren't for the horrible hot and humid weather it would be great. I took a family of 5 to eat a delicious and fresh meal and it was only around $20 US. No where even in Buenos Aires you can eat that cheap. Some places like Terminal 21 upstairs in the food court where you had fabulous food that was really fresh we had meals for as low as $12 for the 5 of us.
Things like 1 hour massage in Bangkok (and much of Thailand) I was paying $6 US per hour. In Buenos Aires I pay $10 per hour at a comparable place.
In Buenos Aires at most places were were still spending on average about $70 US dollars for the 5 of us by the time you added up appetizers, main entre, drinks and dessert.
Some of these places this guy is saying are affordable, aren't really that affordable. Colombia isn't really cheap. And he mentions Cali which is a complete DUMP. No one would want to live there. Colombia things are expensive. Food isn't too cheap, electricty is expensive. He mentions Cartagena which is way overpriced. I find most cities in Colombia to be a dump.
Argentina is VERY cheap and the quality of life is amazing here. Especially Buenos Aires. NOT a place to live if you have to make money here but if RETIREMENT is where you want to live, I don't think it gets any better. I've been to over 575+ cities around the world. About 125 countries. Buenos Aires is amazing to retire to.
