It's true Santiago is not as exciting of a city as Buenos Aires, culturally (but as a new mom working to launch a business it doesn't matter that much to me at the moment). also miss having just about anything within a 10 minute walk (there is a lot of sprawl in Stgo, and I got spoiled for the last several years having a market downstairs and across the street) and all the little mom and pop shops. That's pretty special.
The main thing is that the government in Argentina didn't pay me $40,000 to come and launch a business there (in fact, they inhibited me from starting one)! I wouldn't want to live here long-term, but am excited for the present (and enjoying the abundance of burrito shells, smoked turkey, and amazing prices on seafood, etc.) and may consider living in other regions if the government remains as supportive of business development.
