Immigrants are as burnt out as locals (if not a lot more), just check Blind for 5 minutes.

The difference is just that the livelyhood of sometimes dozens of people back home is on their shoulders, so they just try to power through.

Which company do you work for so that I can avoid it?

Doing so very effectively it seems. :)

I work in Vietnam and I've never heard developers here talk about burnout incessantly like Hacker News does.

Low wages and poor social mobility makes you unable to care about your mental wellbeing, how surprising.

Yes, burnout is a rich country problem, because you otherwise kill yourself at the task because you can't afford not to. Give Vietnam western european wages and within 10 years, burnout will also be a talked about problem. Just because you don't have time to look at something doesn't mean it doesn't exist.
