@eljojo the cost of living in chile is much higher than india while the salary is about the same.
you could make an argument for quality of life, but an immigrant from urban india isn't getting most middle class jobs not without 5+ years of spanish lessons — nor would they want to. a middle class person from india *has* a good quality of life with what they can afford in a place where many people suffer, but you really don't at all once you are middle class.
people aren't looking for a secret hack for immigration, they're looking for 'is it worth it to go somewhere now?' 'what am i giving up everything and everyone i know, and all of my citizenship privileges, for?'
i will be very skeptical if there is significant immigration from china or india to chile. i see the numbers now: other than venezuelans and peruvians, it's largely digital nomad types. it's a very different form of immigration.
if i wanted a lifestyle arbitrage immigration, i would go to taiwan or thailand. while fully aware that's not immigration, that's an extended vacation.
