Anecdotally, a relative of mine worked at a firm in Hong Kong as an Architect, and the firm literally refused to do anything about nearby construction that there was dust blowing into the office ever day. That's the kind of labour standards you may see in Asia :)

She's working in London right now and alot more happier, tbh having grown up there in HK most of my cohort have moved to US or Europe.

Tech as an expat is a bit of bubble, most of the "hard work" in building a career is achieved in the less competitive environment. Growing up there in those cities is another matter, the academic pressure and job market can be soul-crushing. If you don't get into a top university many large firms won't hire you. That's not to say similar things happen in USA, but it's relatively easier to get into Ivy League, and outside of Banking or Law most other careers are willing to give you a chance to prove yourself.
