I agree with you, but some don't; I lived in Cambodia for a while, and there were/are "ex-pats" living there with Khmer wives and children, who speak perfect Khmer, work in Cambodian companies, have been there for 20+ years, and still refer to themselves as "ex-pats". But I think this is might be cultural about the host country. Cambodia is blatantly racist, "Cambodia is for the Khmer people" is a thing there. Any no…
> Cambodia is blatantly racist In my experience, there is nothing special about Cambodia in this regard. You could substitute any poorly developed nation, and you would have similar results. If Cambodia had a GDP per capita similar to Japan/Korea/Taiwan, they would "suddenly" become less racist because they would be much more concerned with economics rather than ethnicity/religion.
I don't think it's wealth that's the differentiator. I think it's partly colonialism and partly culture.

Japan is also, famously, extremely racist. Probably to the same extent that Cambodia is, but I haven't been there so I can't compare.
Colonialism has a lot to answer for in SE Asia. I suspect a lot of the defensive patriotism there is a product of being so badly treated for so long.
And culturally, there are a lot of differences between SE Asia mentality and Anglosphere/Western mentality. I suspect part of it is this, too.
