The Obama administration, by keeping economic growth at anemic levels, has managed to control illegal immigration better than most of its predecessors. The Reagan-era Immigration Reform and Control Act conferred amnesty upon some 3 million illegals in exchange for promises of stepped-up enforcement at the border and in the back office, but the sanctions never quite materialized. Even though some improved security measures were implemented after 9/11, the Bush years saw a 40 percent increase in the population of illegals, according to the Migration Policy Institute

Legal immigration, which is largely driven by our government’s preference that the extended families of previous immigrants be able to join them here, does not closely track the fortunes of the economy. Illegal immigration, on the other hand, is very strongly correlated with the availability of work. It may turn out not to be a growing problem in Obama’s second term, so long as we can count on the Obama administration to provide relatively few employment opportunities for illegal immigrants, along with legal immigrants, the native born, and everybody else not attached to the AFSCME or Big Wind
