Funny how some people like to make vague statements about how it is a host countries fault for not providing immigrants a proportional stake in the economy.
When the United States experienced an explosion of immigration those new citizens were not given anything and for the most part had pretty crappy lives. The vast vast majority of them lived in ethnic (their own ethnicity) slums and over a long period of time, in some cases a few generations, found differing levels of success. Furthermore this vast majority of immigrants (aka OUR GRANDPARENTS, GREAT GRANDPARENTS AND FOR SOME JUST PARENTS) in fact did choose a path of assimilation in some way shape or form AND AT THE SAME TIME preserving whatever level of autonomy they wanted to maintain. I will freely admit that many did indeed succumb to social pressures and that yes, financial success could have been hindered without that assimilation. Yet it is inarguable that the vast majority ENJOYED their new lives and CHOSE to stay rather then return to whatever homeland they came from. Even if that new life was severely crappy by our standards.
I think opportunity is earned and not granted. CAR I think you had a great post as well.
