For example, when contacting with someone outside of the company, you would NEVER refer to anyone in the same company as you with -san honorific (Mr./Ms.) via email even in maximum formality mode, e.g. "I'll forward this to Tanaka-san, head of sales" may be considered rude. Instead, you will have to skip -san, as in "I'll forward this to Tanaka, head of sales."
These small details are so subtle and there's a lot of them. Many people don't really mind if you use it wrong, but some do, so you have to always be cautious with.
I think the easiest way to think might be that you won't refer to your sister/brother with honorifics when talking about them with someone.
When you (an outsider) email a company, everyone in the company who replied to the email are considered belonging to the same group, so they should not use honorifics to refer to themselves regardless whether they are CEO or just random employee (even if you call them with honorifics in internal email.)
There's also another small rule regarding this, such as you can say something like "Uchida, the CEO" (CEOの内田) but NOT "CEO Uchida" (内田CEO) because the title in the latter is being used as a suffix, and considered a honorific (equivalent to -san). It's a weird rule.
The reason? Written Vietnamese is too formal, and they prefer English for getting to the point quickly.
I live in Vietnam, speak Vietnamese, and see millions of people post not-formal, to-the-point things on Facebook and Instagram every day.
Totally different ball game.
I absolutely think there are people where there's a huge gap and others where it's hardly noticeable ;)
(interestingly, my friends point out that I seem to have different personality when using English instead of my mother language)
I assume part of it is due the language used and part due to cultural traits you pick up when you learned it. Would be surprised if there was no feedback loop between language and cultures that use it.

The article goes a bit broader and it's been a few years since I read it in depth, but you might be interested the counter-perspective.
Yes, sure, if anyone claims that such a workplace culture is an inherent, inseparable part of Korean culture, then that's bollocks. But most people aren't saying that. We're just saying that there's a hierarchical culture problem widespread in Korea, right now. Which is absolutely true.
For a less tragic and more comical example of what the culture is like in Korean Air, look up the "Peanut turnaround incident" of 2014 (땅콩회항) which earned Korean Air the memorable nickname of "Peanut Air" (땅콩항공).
(...the nuts were actually macadamia nuts, but "Macadamia Nut Air" doesn't roll off the tongue as nicely.)
I’ve always assumed Asian languages to be very informal as a lot of it has to do with context. At least that’s how some of my friends talk to each other. And one of the reasons why it’s so hard to blend in. It could also be possible that they rarely talk formally in person, and I’ve yet to experience it.
With Korean, spoken language among roughly same-age friends is informal, of course. But if someone is older, then there's a different ending, unless you know them well enough to speak in informal language.
If you're speaking to your boss there's a different level of formality, and people like your grandparents get honorifics which are also conjugated, but alongside with formality.
It also reinforces social pressures of obeying your boss/elders, which stem from Korea's roots in Confucianism/Neo-Confuncianism.
It's no wonder people like to use English sometimes.
I'm not sure what you mean by this, but if you're thinking about "East Asian languages omitting 'necessary' grammatical parts all the time", then you might be talking about this:
https://en.wikipedia.org/wiki/Pro-drop_language
Note that this is a grammatical phenomenon exhibited by some languages (i.e., the characteristics of a language as a whole). Formality/informality is a concept associated with a particular "speech" inside a language, which is orthogonal to this. (You can say a particular speech in English is formal or informal, but it makes little sense to say that "English" as a whole is a formal or informal language.)
My tl;dr would be "the US is big and complicated." I've seen people working stressful service jobs be incredibly polite in Houston, and baristas being checked-out jerks in small-town Colorado. Overall, I would say that people tend to be more polite when they have more mental energy to spend. That tends to be in quieter towns, but not always.
Are there companies with an overwork culture in the US? Oh yeah, definitely. But how many expect everyone to work, say, 9-7:30 at a minimum, plus some time most Saturdays, and to go out to the bar after work as a team multiple times a week? That would be extremely rare, maybe some finance companies and startups have that kind of culture, but not many.
