Expats outside of BsAs


I don´t know if there are many expats living outside of gran BsAs but prices are mainly a lot lower there.
Why aren´t there many expats outside of BA?
I am in Salta a few days now and eventhough it´s a lot different then BA it´s nice, cheap and safe. I can see somebody wanting to live there. But as I understand it summer gets really hot there, but that´s in BA as well. But maybe you can travel a bit then or go back to your native country a few months
I have never tried it but I would think there is plenty of english teachers, there are lot´s of people who are well-off and are probally willing to pay for English teachers.
It must be pretty good for hiking, fishing, hunting and biking as well if you like that kind of stuff
