Has there been a group of people who have immigrated to the US in some significant number and on average not thrived much greater than the lot they started with? Are the results similar in Western Europe or the Commonwealth? Example, would the Indians or Arabs significantly improve thier lot on average about the same as they would in the US on avg?
Many of the recent non Western European groups immigrating over (Arabs, Indians, Asians, Greeks, Russians, and I think north Africans) out perform the more “traditional” white American natives in school. Is this true in Europe/the Commonwealth as well? Is there any studies on the reason why that is for this trend?
