For the most part, I guess not. We certainly have adopted a lot of their culture into our own, however, that being said, many of these Immigrants (illegal or not) have not assimilated as the Irish, Italian, Dutch, French, German, etc immigrants before them... One of the greatest qualities of America is that we take these people in, make their culture a part of our own 'collective culture,' and create a great social society in which one can identify with one another.
I totally agree with this. It's much more interesting and beneficial for everyone to add to a collective culture.
The three stand-out multicultural countries that come to mind are: US, Canada, Australia. None are free from problems, to be sure, but they seem to be heading in the right direction and generally function well.
It works well as long as everyone agrees to be bound by a common set of laws & core values.
People talk metaphorically of having a cultural "salad" rather than a "melting pot" - so things work together, but manage to keep their own identities, rather than melting into an indistinguishable mass of sameness.
I always think of Dearborn, Michigan when people talk about issues with the Islamic community in Iraq, France, Germany, etc. Why do they get along in the US, but not outside? My theory has always been that they were welcomed as friends and neighbors, and their culture remains an important part of SE Michigan.
I always think of the city of Toledo in Spain, where Christians, Muslims and Jews lived for hundreds of years in peaceful cooperation, yet retained their language, food, architecture etc.
I've always wondered about this myself, and can only assume that it comes from a greater understanding of others when exposed to them/ their culture/ language etc. -As well as other factors that cause conflict in the first place:
Every war that ever was has been fought for a resource of some kind, wether its land, oil, water, gold, whatever.
Religion, race, and any other difference simply adds fuel to the fire/ provides justification & propaganda for the conflict.
