Fifteen years ago, I was offered a job at Yahoo, in California, making close to four times my then-current salary in Mexico City. About US$70K a year. That money, even today, is a shitload of money for me.
Of course, I declined. I declined even being unaware of the ridiculously high costs of living in the San Francisco Bay area — I declined because I didn't want to stop living at a city I love, close to my family and life-long friends. But yes, digging a bit deeper into what US$70K a year would be for a living there... I never looked back.
Currently, I have been employed for 11 years at the same place. The peso has slided against the dollar, so I still make slightly over US$20K a year. I live a very nice life in a house very well located. I don't have much savings, but then again, I did have something to fall on when my kids were born. Have never had a loan. My wife does not currently work, but we estimate she can go back to doing so in 2-3 years, and then we will get some savings again.
What would there be in there for me going for a life at a country that will always see me as a foreigner? Not much, I guess.
