I've seen this sentiment posted before and it's pretty much untrue. At 120k/year, even spending 4K/month on rent, your leftover pay is still more than my gross salary. I know SF is expensive, but if you can't have a nice QOL on a the leftovers of a 120k salary, your location isn't the problem.
$120k in SF probably amounts to take home just under $6k/mo. $4k goes to rent, so you have $2k for everything else.
That's not a great QOL. For comparison, I ran the Mexico City / SF cost of living on Numbeo[0]. $38k in Mexico City would need to be $140k in SF for comparable quality of life.
(side note -- this COL calculator is super neat! anyone have any evidence of the accuracy?)
So, for reference, after taxes a single person takes home what? $80k. That's about $6,666 per month, leaving $2666 after paying rent. That's not including food. Also for reference, when I lived in a South American country, rent was running about $400 a month, but even if it was $700, wouldn't you be doing better in South America? You can't ignore the fact that food and services are extraordinarily cheaper due to the lower cost of living.
