For Dubai specifically, there is a mix of foreigners, a large percentage being labourers from South Asia. The orderliness we see, I think is largely due to strict* and harsh laws.
Absolutely agree, I had my manager play it for me in my first company. And since I did not learn how to play it effectively or the importance of it, I think I suffered/suffering in my subsequent job(s).
IMHO, it would be a win even if it allowed movement between Canada and the EU as freely as Canadians and Americans can currently move between Canada and the US. That would give Canadian snowbirds easier (longer) access to warm EU destinations, while those destinations would benefit from the additional revenue.
I am assuming you are somewhere in Europe and given your apparent dislike for Indians, let's look at an alternative narrative. As a Canadian of East Indian origin, I can tell you that if these individuals are Canadian citizens, they are very unlikely to leave Canada for Europe. If they are not Canadian citizens, the point is moot anyway. In fact, I would expect more European citizens of South Asian origin to move to Canada, where English is spoken, integration is generally easier and salaries are far higher. So, breathe easy.
