Rather than use your personal experiences for the basis of my post how about a general history of how North America was settled. If Europe was down to 5 countries that supplied all the immigrants for NA it would show that the people from the UK tended to bunch up with other people from the UK, just as people from France would connect with the people from France and that would apply any ethnic group that came over. The Far east is no different and they would be like the 2nd wave. There are strong ties to the homeland in all of those cases and rather than try and abandon the past for what should be Canadian is a step that is avoided as much as possible. Remnants of the 1st wave still exist as they are the ones that call the shots (as much as possible for a puppet) in Politics and in Business and in Banking.
If the above was not true today you would not be able to find ethnic communities anyplace. You can find them in any city, the bigger the city the more ethnic groups there are. Cities also divide themselves based on wealth and that can easily be shown to show the 1st wave are the rich and the 2nd wave are the poor. That division is also on that is not easily crossed.
Overlay the two and you have the reason cities and nations are always in turmoil. Division of any kind causes stress for somebody. The rich just give a fuk, as long as they are the top of the food change. Put them at the bottom and suddenly all their old ways of doing things should be changed. No wonder the rich are despised in general.
