President Obama likes to talk about how the immigration system is "broken," most recently on Thursday when he ordered a review of deportation practices after a meeting with members of the Congressional Hispanic Caucus.

But is it? If so, where's the evidence?

The message of a "broken" immigration system is the cornerstone of the lobby campaign for an immigration "reform" bill that's primarily aimed at legalizing some 11.5 million illegal immigrants already in the United States, the overwhelming majority of whom come from Mexico and Central America. In doing so, the bill would eliminate the diversity visa lottery and other programs that allow people from other parts of the world who want to become Americans to realize their dreams.

This is among the clearest indications of the nakedly-political motives behind the messaging campaign: Ethnic lobbies are looking to expand their power and the Democratic Party wants to tap into a likely source of votes.

"Reform" advocates are deliberately confusing migration to the United States for economic purposes with immigration by people choosing to become Americans. They are exploiting migrant workers for their own agenda, rather than providing them with a real choice, and Republican politicians and business groups are falling for the ruse.

If these groups really cared about increasing work opportunities in the United States for Mexicans and Central Americans, they would support a treaty that would allow the free legal flow of workers across the region without forcing them to chose between their jobs and their nationality. The United States has trade agreements with Mexico and many Central American countries, which allow for the free flow of goods and services across the border. Why not add labor to the mix as well?

As for those who really want to become Americans, there's a naturalization system in place that works just fine.
