And how many immigrants to Ireland have actually assimilated to Irich culture? That will be the telling point, and what a large part of the problem is here in the US. It isn't that there have been so many, though it *is* rapidly becoming a problem, it's the breakdown of the traditional assimilation that is really causing the headaches.
There have long *been* people of Mexican heritage here in the US, and the majority of those assimilated just fine. These folks truly did, and still do add to our nation, even though they were *not* treated with absolute fairness from the start, a fact which is readily admitted.
The more recent arrivals, on the other hand, have few skills, little to no education, are unwilling to assimilate, and sadly, are easy prey for the unscrupulous to exploit. I've seen much of it, and even more has my wife, who is herself an Hispanic first generation, legal immigrant. There is more to many conservatives' opposition to the unchecked fiasco we have now, than racism (little to any of that), economic concerns (more of a concern), or security concerns (the greatest concern at the moment to most)...

They are not assimilating too good - ghettos are on the rise here. It's strange to think - Ireland, like America, has historically been a melting-pot (e.g. the Normans and Vikings), but thanks to Multiculturism - that has all changed.
