Is it true that the average Chinese person is irreplaceable in their field?

Ok so I watched a funny video of an old Chinese woman who grew up in China before the economic reform, and she is talking about how [stereotypically] Chinese people are extremely hard working, focusing on getting ahead in their field rather than cultivating relationships or going to social events. But you see a lot of posts contrasting this stereotype against the reality, saying how a lot of people are actually lazy and that's what causes all these wars on instant noodles and Tiktok and stuff. <br><br>But then I was listening to Chinese commentary on this and [they say] in recent years, for various reasons, it's becoming more and more common for people to have a low work ethic. Some people say [it's because] everyone is now a "bare branch" (a bachelor with no siblings), but another popular theory is that a lot of people were getting ahead through sheer hard work in the 90s-2010s, and now everyone wants to be "efficient"/lazy and only do the bare minimum, and retire early etc. And this makes sense because when there's a whole generation of people just working hard while the owning class can just sit at the top and reap the benefits, there's no room for upward mobility. The owning class can just pay you peanuts and make you work your butt off, which has no end in sight.<br><br>However, I keep seeing posts of immigrants in America from India or Vietnam or whatever talking about how they work in tech and they have this Chinese colleague who instantaneously responds to their emails and is up at 1am working, or their boss is Chinese and talks about how they need to work twice as hard as some white guy instantaneously responding to emails, and they're all just so impressed. <br><br>So... what's going on?
