Linda Chavez’s new column regurgitates the conventional wisdom circa 1973 about how immigrants and their children are doing just fine, upward mobility, just like your bubbe from Bucharest, etc. In fact, scholars are now focusing on what they’re calling the “immigrant paradox,” wherein the descendants of immigrants, especially Hispanic immigrants, are not following the path of earlier newcomers. In fact, a new longitudinal study of Mexican immigrants and their children, grandchildren, and great-grandchildren finds that, compared to the second generation (the children of the immigrant), the fourth generation (the great-grandchildren) have higher dropout rates, lower educational attainment, lower incomes, higher poverty rates, lower home-ownership rates, and lower net worth. My colleague David North chews over some of the possible reasons for this, but the idea that everything’s hunky-dory and we should take another 10–15 million immigrants over the next decade is delusional.
