National Review writer Rich Lowry is now actually calling for a reduction in legal immigration:
"The real answer is to scale back legal immigration [emphasis mine] and control the nation’s borders, so low-income workers don’t have to compete against new immigrants, especially people who have no right to be here."
Lowry also wrote:
"Economics 101 says that the more poorly skilled workers there are, the less they will make. Indeed, according to the National Research Council, roughly half of the decline in real wages for native high-school dropouts from 1980 to 1994 was due to immigration."
The NR has been railing against illegal immigration, multiculturalism, and especially immigrants who present a direct national security threat, but has not generally been so hard on legal unskilled immigration. It’s good to see the NR taking a tough stance on legal immigration, because any immigration reform that does not include the reduction of legal unskilled immigration is not taking care of the main thrust of our immigration problem–the importation of a persistent, dependent, and resentful underclass.
 Even notwithstanding Bell Curve-type theories, it is clear that something is tending to hold down some non-white immigrant groups but not others, and that this something is not going away any time soon (for example, second- and third-generation Latino immigrants continue to lag behind native-born whites (on average, of course) in income and education). Given the general success of many non-white and/or previously discriminated against groups (South Asians, many East Asian groups, and Jews), it seems unlikely that the "something(s)" holding down some immigrant groups include white racism or "institutional racism."
