[Edit] on second glance, my original datapoint for Google was questionable, but it looks like Lyft/Amazon definitely gives offers in the 50k-70k USD range.
Search "sueldo ingeniero Google Mexico" and you see wages like $30k USD which is already +$10k over the Mexico average for software, so way more realistic.
How do I move to Mexico?
Mexico's immigration policies are deliberately designed to exclude most people who aren't wealthy retirees and don't have familial ties.
What is Mexico's visa policy w.r.t. NAFTA/CUSMA professionals? Can I just get in temporarily as a software engineer akin to TN-1 in the USA?
It reveals nothing about the CoL of the city.
So while low cost of living countries offset their low wages with cheaper housing, food and local services, imported stuff still costs the same and is relatively expensive as a result. Basically in those countries it really sucks to buy a computer, camera, even cars.
It makes enough sense, Microsoft isn't a charity, they're selling the console at a fairly competitive price already in the US, it's not going going to magically get cheaper just because it crossed a border, but it was still surprising to see that.
They of course are region encoded, but I suspect nearly anyone who frequents Hacker News knows how to get around that.
Only some things are particularly cheap in Mexico like labor and anything where labor is the main input, like services.
And some things that you'd think would be in reach of a Mexican software developer, like sending your kids to a decent private school, are not.
