Singapore is a counterexample to the grandparent post. It's very much a "heterogenous" culture, if the word "heterogenous" has any meaning at all, with four (!) official languages and a lot of immigration. It could not be described as "chaotic" or "disorderly."
The unsubtle explanation from someone who is not a huge Singapore fan (or from someone who is?) might be that this is simply the power of well-engineered, highly authoritarian government. But it's certainly not about choosing homogeneity or eschewing immigration.
Singapore is 75% Chinese, and immigration levels are calibrated to maintain that ratio. Accounting for religious diversity, US hasn’t been as homogenous as Singapore since the 1800s. And Singapore is also a country where the top-down authoritarian government is run based on the vision of LKY, who himself is distinctly inspired by a mix of Confucianism and Anglo culture. The other cultural groups are given wide latitude within their sphere of influence, but none have any imprint on the government and institutions. It’s like if Americans agreed that WASP culture would always dominate the government and civil institutions.

This didn't jibe so I looked up the figures and I still don't understand why you'd write this. To be honest I don't understand why you've written most of what you've written on this thread, but, did you mean to write "ignoring religious diversity...?" The US is 63% Christian. The largest religious group in Singapore is the Buddhists, at... 31%? And unlike in the United States, two minority groups in Singapore (Christians, Muslims) have strong representation in the population, whereas in the US, not so much.
Which I guess would leave things like language, of which they have four official ones and quite a few others, with a bilingual education mandate that demands everyone learn English but recognizes that they've probably got their own as well, IIRC.
There's racial makeup, if that matters to you (I get the feeling it does). In terms of cultural dominance I would reject the idea that there's something massively different about a 69% white majority vs a 74% Chinese majority. The second on their list is Malay at 13.5% and the second on our list is Black at 12.4% and my God why are we even having this conversation
I'm pretty sure the explanation for the undeniable order there is the completely obvious explanation that does not involve "homogeneity" or immigration. It's the authoritarian system of government.
If you compare like with like, the US is more diverse on almost every dimension except language. Catholic/Protestant is a major dividing line. And if you are going to say “white” is a category, then Singapore is virtually 100% “Asian.” If you want to talk about ethnic groups, then the largest US ethnic group is German Americans, which are only about 25% of the population.
And yes the homogeneity helps Singapore’s orderliness. The overwhelming majority of the population is Asian, who in general are more collectivist and orderly than say Italians.
