I understand the basics of economics, but I must say this pay gap is pretty disappointing for me too. Yes, I'm living in a country where the cost of living is much cheaper, but the same country is classified as "not free" by Freedom House. The only reason I still live here is to save money before I, hopefully, move to any first-world country.
I want everyone to understand that the cheap cost of living usually comes with restrictions on human rights and mental illness.
